zebrafish

A fish model of vertebrate embryological development. Embryos ar translucent and large number of known (and manufactured) mutants.

(More? Other Embryos - Zebrafish)

ZIFT

Acronym for Zygote Intra Fallopian Transfer, a in vitro fertilization procedure in which eggs are collected from a woman's ovaries and fertilized outside her body. A laparoscope is then used to assist in placing the resulting zygote (fertilized egg) into the woman's uterine (fallopian) tube through small incisions in her abdomen.

ZP1

Acronym for Zona Pellucida Protein, a glycoprotein found in zona pellucida surrounding the egg.

(More? Zona pellucida | Week 1 - Fertilization | Week 1 - Oogenesis | zona pellucida binding protein 1 | OMIM - ZP1)

ZP2

Acronym for Zona Pellucida Protein 2, a glycoprotein found in zona pellucida surrounding the egg. Before fertilization ZP2 binds spermatozoa. After fertilization ZP2 is proteolytically cleaved as an initial block to polyspermy.

ZP3

Acronym for Zona Pellucida Protein 3, a glycoprotein found in zona pellucida surrounding the egg required for initial zona matrix formation and during fertilization for species-specific sperm binding. Now thought to exist in 2 isoforms ZP3A and ZP3B (a second polymorphic allele).

ZPBP1

Acronym for Zona Pellucida Binding Protein 1 A spermatozoa protein found located on the acrosome surface.

(More? Week 1 - Fertilization | Week 1 - Oogenesis | zona pellucida binding protein 1)

zona pellucida

(Latin, zona pellucida = transparent zone) A specialized [E.htm#extracellular_matrix extracellular matrix] surrounds the developing [O.htm#oocyte oocyte] (egg, ovum) within the ovary and follwing ovulation. It consists of three types of glycoproteins ZP1, ZP2 and ZP3 which have different roles in fertilization. Following fertilization, the zona pellucida also surrounds the blastocyst during the first week of development, from which it "hatches". The zona pellucida has a role in fertilization, sperm binding, preventing [P.htm#polyspermy polyspermy], [B.htm#blastocyst blastocyst] development and preventing premature implantation (ectopic pregnancy).

zona pellucida binding protein 1

(ZPBP1) A spermatozoa protein found located on the acrosome surface which has a role during spermiogenesis (acrosome compaction, Sertoli-spermatid junctions) and also binds the zona pellucida during fertilization.

zoonotic disease

An animal disease that can be transmitted to humans. This can be through contact with animals (pets, farm animals, wildlife) or their products (milk, meat, waste).

(More? Toxoplasmosis | [Q.htm#Qfever Q Fever])

zygote

The first diploid cell that forms following fertilization by fusion of haploid [O.htm#oocyte oocyte] (egg) and [S.htm#spermatozoa spermatozoa] (sperm) resulting in the combination of their separate genomes.

(More? Week 1 Notes)

zygote intrafallopian transfer

(ZIFT) A procedure in which eggs are collected from a woman's ovaries and fertilized outside her body. A laparoscope is then used to assist in placing the resulting zygote (fertilized egg) into the woman's uterine (fallopian) tube through small incisions in her abdomen.

zymogen

Term used to describe the precursor inactive form of an enzyme.
