<pubmed limit=5>TGF-β Embryology</pubmed>
The TGF precursor protein has three distinct regions:
- signal peptide - targets it to the endoplasmic reticulum and secretion
- propeptide - or the latency associated peptide
- mature peptide - cleaved from the precursor protein and is actively involved in signalling
- cleaved by Furin - a convertase
- cleaved at a dibasic arginine-X-X-arginine (RXXR) site
Expressed at the fetal-maternal interface and implicated in the promotion of implantation and post-implantation development.
- active peptide forms a hetero- or homodimer
- binds to a specific TGF-β Type II receptor
- Type II receptor then recruits a TGF-β Type I receptor
- phosphorylates it via its serine/threonine kinase domain
- phosphorylated Type I receptors then phosphorylate receptor-associated Smad proteins (R-Smads), including Smad1/5 and Smad2/3
- Type II receptor - MlTgfRII
- Type I receptors - MlTgfRIa, MlTgfRIb, and MlTgfRIc
- R-Smad proteins are composed of two main functional domains
- Mad-homology domains 1 and 2 (MH1 and MH2)
- Smad1/5 - associated with BMP-like signalling.
- Smad2/3 - associated with TGF-β-like signaling.
Mothers against decapentaplegic homolog 5 (SMAD5) is a transcriptional modulator activated by BMP (bone morphogenetic proteins) type 1 receptor kinase.
Bone morphogenetic protein 15
BMP15 evolution among family members
Growth Differentiation Factor 1
Growth Differentiation Factor 9 (GDF1) in involved in early left-right patterning. Also expressed in the nervous systemin late-stage embryos.
Growth Differentiation Factor 9
Growth Differentiation Factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15) are both members of the transforming growth factor-β (TGF-β) superfamily. They have both been identified as growth factors required oocyte to granulosa cell signaling for ovarian follicle development (folliculogenesis).
A recent study in pig has shown that oocyte-derived BMP15 but not GDF9 is required for down-regulation of connexin43 expression leading to a decrease in intercellular gap junction communication in granulosa cells.
About OMIM "Online Mendelian Inheritance in Man OMIM is a comprehensive, authoritative, and timely compendium of human genes and genetic phenotypes. The full-text, referenced overviews in OMIM contain information on all known mendelian disorders and over 12,000 genes. OMIM focuses on the relationship between phenotype and genotype. It is updated daily, and the entries contain copious links to other genetics resources." OMIM
