Summary

TEX101 (testis expressed 101, HGNC:30722) is a protein-coding gene on chromosome 19q13.31, encoding Testis-expressed protein 101 (Q9BY14). Plays a role in fertilization by controlling binding of sperm to zona pellucida and migration of spermatozoa into the oviduct.

Predicted to be involved in binding activity of sperm to zona pellucida; flagellated sperm motility; and regulation of flagellated sperm motility. Predicted to be located in acrosomal vesicle; extracellular region; and plasma membrane. Predicted to be active in plasma membrane raft.

  • TEX101 is a cancer-testis (CT) gene useful for detection of CML. It was expressed in 30% of CML patients, but not in healthy donors. Unlike many CT genes, overexpression of TEX101 was not shown to induce immunologic responses in these samples. (PMID:22588436)

  • Overexpression of TEX101 is associated with breast tumors. (PMID:25994570)
  • Study provides evidence that spermatozoa of rs35033974 homozygous men have substantially reduced levels of TEX101 and could be used as a model to elucidate the precise TEX101 function. Because TEX101 seminal plasma levels were found significantly lower in heterozygous than in WT men, rs35033974 status could be considered in TEX101 diagnostics. (PMID:30429210)

Function. Plays a role in fertilization by controlling binding of sperm to zona pellucida and migration of spermatozoa into the oviduct. May play a role in signal transduction and promote protein tyrosine phosphorylation.

Subunit / interactions. Interacts with VAMP3. Interacts with LY6K. Interacts with DPEP3; co-localized on the cell surface of spermatocytes, spermatids, and testicular spermatozoa, co-localized only in cytoplasmic droplets of caput and corpus epididymal sperm. Interacts with ADAM5.

Subcellular location. Cell membrane. Membrane raft. Cytoplasmic vesicle. Secretory vesicle. Acrosome. Secreted.

Tissue specificity. Detected in testis and spermatogonia. Not detected in spermatocytes. Detected in blood leukocytes.

Post-translational modifications. N-glycosylated; by high mannose and/or biantennary complex and/or certain types of hybrid oligosaccharides; possesses different oligosaccharides chains according to its subcellular localization in the testis. Sheds from membrane raft by ACE and released from the cell surface of epididymal sperm while it passes through the caput epididymis leading to disappearance of TEX101 on spermatozoa; is essential to produce fertile spermatozoa.
