The Y chromosome is much smaller than the X chromosome and contains 50 million base pairs encoding approximately 200+ genes. The Sry gene (location Yp11.3), found in 1990, encodes is responsible for male sex determination. SRY mutations lead to XY sex reversal in humans, and XX mice with an SRY transgene develop as fertile males. Interestingly, the laboratory rat, ''Rattus norvegicus'', has at least 6 full length copies of the Sry gene.{{#pmid:17408480|PMID17408480}} | ||

* ''' | * '''XY oocytes of sex-reversed females with a Sry mutation deviate from the normal developmental process beyond the mitotic stage'''{{#pmid:30289439|PMID30289439}} "The fertility of sex-reversed XY female mice is severely impaired by a massive loss of oocytes and failure of meiotic progression. This phenomenon remains an outstanding mystery. We sought to determine the molecular etiology of XY oocyte dysfunction by generating sex-reversed females that bear genetic ablation of Sry, a vital sex determination gene, on an inbred C57BL/6 background. These mutant mice, termed XYsry- mutants, showed severe attrition of germ cells during fetal development, resulting in the depletion of ovarian germ cells prior to sexual maturation. Comprehensive transcriptome analyses of primordial germ cells (PGCs) and postnatal oocytes demonstrated that XYsry- females had deviated significantly from normal developmental processes during the stages of mitotic proliferation. The impaired proliferation of XYsry- PGCs was associated with aberrant β-catenin signaling and the excessive expression of transposable elements. Upon entry to the meiotic stage, XYsry- oocytes demonstrated extensive defects, including the impairment of crossover formation, the failure of primordial follicle maintenance, and no capacity for embryo development. Together, these results suggest potential molecular causes for germ cell disruption in sex-reversed female mice, thereby providing insights into disorders of sex differentiation in humans, such as "Swyer syndrome," in which patients with an XY karyotype present as typical females and are infertile." | ||
* '''Alterations of sex determination pathway in the genital ridges of males with limited Y chromosome genes'''{{#pmid:30285093|PMID30285093}} "We previously demonstrated that in the {{mouse}} only two Y chromosome genes are required for a male to produce an offspring with the help of assisted reproduction technologies (ART): testis determinant Sry and spermatogonial proliferation factor Eif2s3y. Subsequently, we have shown that the function of these genes can be replaced by transgenic overexpression of their homologues, autosomally encoded Sox9 and X-chromosome encoded Eif2s3x. Males with Y chromosome contribution limited to two (XEif2s3yOSry), one (XEif2s3yOSox9 and XOSry, Eif2s3x) and no genes (XOSox9, Eif2s3x) produced haploid germ cells and sired offspring after ART. However, despite successful assisted reproductive outcome, they had smaller testes and displayed abnormal development of the seminiferous epithelium and testicular interstitium. Here we explored whether these testicular defects originated from altered pro-testis and pro-ovary factor signaling in genital ridges at the time of sex determination." | |||

Introduction
Humans have 23 pairs of chromosomes, 22 autosomes and a pair of sex chromosomes. Males have one X and one Y chromosomes (46, XY) and females have a pair of X chromosomes (46, XX). The Y chromosome is much smaller than the X chromosome and contains 50 million base pairs encoding approximately 200+ genes. The Sry gene (location Yp11.3), found in 1990, encodes is responsible for male sex determination. SRY mutations lead to XY sex reversal in humans, and XX mice with an SRY transgene develop as fertile males. Interestingly, the laboratory rat, Rattus norvegicus, has at least 6 full length copies of the Sry gene.[1]
Placental male mammals have SRY protein transcription factor that activates Sox9 for testes formation. SRY evolved as a hybrid gene of Dgcr8 expressed in the developing placenta and Sox3 expressed in hypothalamic development.
SRY encodes a 204 amino acid protein that is a member of the HMG (High mobility group) box class of DNA-binding proteins. Transcription factors bind to specific sites of DNA and regulates the transcription (expression) of other genes.
The male-specific region of the human Y chromosome was originally called the non-recombining portion of the Y chromosome (NRY). This region consists of three different classes of euchromatic sequences:
- X-transposed - 3-4 Ma transposition 99% identical to human Xq21
- X-degenerate - 14 single copy or 13 pseudogene homologs of X-linked genes
- ampliconic sequences - Sequences with strong identity to other regions of Y
The Y and X chromosome are both transcriptionally silenced during spermatogenesis, at primary spermatocyte stage onward, by a process called meiotic sex chromosome inactivation (MSCI). (More? Meiosis)

History
- 1916 - Bridges[5][6] describes the sex chromosomes of Drosophila melanogaster and shows that sex is determined by the X:autosome ratio
- 1923 - Painter[7] describes the Sex chromosomes in mammals - it is assumed that sex determining mechanism will be the same as Drosophila
- 1959 - Ford et al.[8] find a human XO and female - Turner's syndrome
- 1959 - Jacobs and Strong[9] find an XXY male - Kleinfelter's syndrome
- together these prove that the Y chromosome determines sex and not the X:autosome ratio
- 1989 XX males found that carry a very small portion of Y chromosomal DNA (60kb)
- using DNA from these males a search for the testis determining gene, TDF or TDY led to the isolation of the gene
- gene called SRY because it comes from the Sex-determining Region of the Y chromosome. It is the molecular "switch" that determines sex in humans
Y Chromosome Genes
- ZFY (Yp11.2) zinc finger transcription factor, required in males for spermatozoa or testis maturation.[10] A similar sequence called ZFX, has been identified on the X chromosome, that in humans escapes X inactivation.

SRY
Sry (sex-determining region on the Y chromosome) gene was found in 1990 on the Y chromosome and the first Sox gene identified, the sry gene encodes a "testis-determining factor" a 204aa protein (Mr 23884 Da).
Sry acts as a transcriptional activator (HMG type-high mobility group) binding to DNA and initiating male sex determination then regulating male development. The protein sequence is shown on this current page and the full genebank entry can also be seen. The sry protein has a HMG box that binds DNA by intercalating in the minor groove. Read about the mapping of the testis determining factor which is SRY.
The actual gene targets of SRY are still being determined but at least one downstream gene Sox9 has been identified. Another gene Dax1 (nuclear hormone-receptor superfamily member) when expressed as a transgene will antagonize Sry and also force dosage-sensitive sex reversal.

SOX
Sox is an acronym of "Sry-related HMG box" and there have now been identified at least eight groups of genes that belong to this family with different functions. (for review see[12]) The "HMG box" is a region that functions for DNA binding, DNA bending, protein interactions, and nuclear import or export.
The high mobility group (HMG) domain is a 79 amino acid protein region.

SRY Nuclear Import
A model for nuclear import of Sry from normal males and XY females.[13]
The distinct nuclear localization signals (NLSs) of SRY use different import pathways.
- cNLS - recognized by IMPβ, docks the transport complex at the nuclear pore complex (NPC) and is then translocation through. After nuclear entry of the complex, RanGTP binds to IMPβ to trigger release of SRY; DNA binding by SRY may also facilitate the release process.
- nNLS - mediates nuclear import through a novel pathway not utilizing conventional nuclear import factors such as IMPs but an unidentified "transport factor" (TF) suggested to be calcium-calmodulin.
Sry Target Genes
Cerebellin 4 precursor (Cbln4) - encodes a secreted protein expressed in Sertoli cells in the developing gonad.[14]
Androgen receptor - SRY interacts with and negatively regulates this receptor transcriptional activity.[15]
DAZ
DELETED IN AZOOSPERMIA 1 (DAZ1) gene encodes an RNA-binding protein that has a role in spermatogenesis.[16]
The DAZ cluster arose during primate evolution by:
- transposition of the autosomal gene (on chromosome {{Chr3}) }to the Y
- amplification and pruning of exons within the transposed gene
- amplification of the modified gene
- Links: OMIM - DAZ1
Testis-specific Protein Y Chromosome
Testis-specific Protein Y Chromosome (TSPY) is an ampliconic gene on the Y chromosome with an unknown function, though the protein that has been shown to interact with gonadoblastoma. A recent study suggests that TSPY serves as a repressor in androgen-induced tumor development in testicular germ-cell tumours (TGCTs).[17]
Pseudoautosomal Regions
These are two intervals of sequence identity at the tips of both the Y and X chromosomes, the human pseudoautosomal regions PAR1 and PAR2.[18] Loss of PAR1 has been associated with male sterility. |
