Zinc finger Y-chromosomal protein is a protein that in humans is encoded by the ZFY gene of the Y chromosome. [3] [4]
This gene encodes a zinc finger-containing protein that may function as a transcription factor. This gene was once a candidate gene for the testis-determining factor (TDF) and was erroneously referred to as TDF. [4]
Humans express a single ZFY gene with two splice variants, while mice express two paralogous copies, Zfy1 and Zfy2. [5] During spermatogenesis, wrongful expression of either Zfy1 or Zfy2 results in programmed cell death, apoptosis, at the mid-pachytene checkpoint. In mice, Zfy genes are necessary for meiotic sex chromosome inactivation (MSCI). In Zfy knockout spermatocytes, sex chromosomes are incorrectly silenced. Thus, Zfy performs three functions at the mid-pachytene checkpoint: (1) promote MSCI, (2) monitor MSCI progress, and (3) execute cells, via apoptosis, that fail to undergo MSCI. [5]
In humans, ZFY is most broadly expresses in the testis and prostate. However, 20 other tissues also express ZFY, such as esophagus, urinary bladder, bone marrow, small intestine, appendix and gall bladder. [6]
Disorders associated with the ZFY gene include campomelic dysplasia, cystadenofibroma, and Frasier syndrome. [7]
The X chromosome is one of the two sex chromosomes in many organisms, including mammals, and is found in both males and females. It is a part of the XY sex-determination system and XO sex-determination system. The X chromosome was named for its unique properties by early researchers, which resulted in the naming of its counterpart Y chromosome, for the next letter in the alphabet, following its subsequent discovery.
David C. Page is an American biologist and professor at the Massachusetts Institute of Technology (MIT), the director of the Whitehead Institute, and a Howard Hughes Medical Institute (HHMI) investigator. He is best known for his work on mapping the Y-chromosome and on its evolution in mammals and expression during development. He was cited by Bryan Sykes in Adam's Curse: A Future Without Men.
Sex-determining region Y protein (SRY), or testis-determining factor (TDF), is a DNA-binding protein encoded by the SRY gene that is responsible for the initiation of male sex determination in therian mammals. SRY is an intronless sex-determining gene on the Y chromosome. Mutations in this gene lead to a range of disorders of sex development with varying effects on an individual's phenotype and genotype.
Spermatocytes are a type of male gametocyte in animals. They derive from immature germ cells called spermatogonia. They are found in the testis, in a structure known as the seminiferous tubules. There are two types of spermatocytes, primary and secondary spermatocytes. Primary and secondary spermatocytes are formed through the process of spermatocytogenesis.
Y linkage, also known as holandric inheritance, describes traits that are produced by genes located on the Y chromosome. It is a form of sex linkage.
The synaptonemal complex (SC) is a protein structure that forms between homologous chromosomes during meiosis and is thought to mediate synapsis and recombination during prophase I during meiosis in eukaryotes. It is currently thought that the SC functions primarily as a scaffold to allow interacting chromatids to complete their crossover activities.
Deleted in azoospermia-like is a protein that in humans is encoded by the DAZL gene.
Testis-specific Y-encoded protein 1 is a protein that in humans is encoded by the TSPY1 gene.
Zinc finger E-box-binding homeobox 1 is a protein that in humans is encoded by the ZEB1 gene.
Transcription factor SOX-5 is a protein that in humans is encoded by the SOX5 gene.
Lysine-specific demethylase 5D is an enzyme that in humans is encoded by the KDM5D gene. KDM5D belongs to the alpha-ketoglutarate-dependent hydroxylases superfamily.
Doublesex and mab-3 related transcription factor 1, also known as DMRT1, is a protein which in humans is encoded by the DMRT1 gene.
Synaptonemal complex protein 3 is a protein that in humans is encoded by the SYCP3 gene. It is a component of the synaptonemal complex formed between homologous chromosomes during the prophase of meiosis.
Protein boule-like is a protein that in humans is encoded by the BOLL gene.
Zinc finger X-chromosomal protein is a protein that in mammals is encoded by the ZFX gene of the X chromosome.
Kelch domain-containing protein 3 is a protein that in humans is encoded by the KLHDC3 gene.
Transcriptional repressor CTCFL also known as BORIS is a protein that in humans is encoded by the CTCFL gene.
HORMA domain-containing protein 1 (HORMAD1) also known as cancer/testis antigen 46 (CT46) is a protein that in humans is encoded by the HORMAD1 gene.
The meiotic recombination checkpoint monitors meiotic recombination during meiosis, and blocks the entry into metaphase I if recombination is not efficiently processed.
Early growth response protein 4 (EGR-4), also known as AT133, is a protein that in humans is encoded by the EGR4 gene.
