TissueNA
Tissue SpecificityTestis and ovary (at protein level). Predominantly expressed in testis. Specifically expressed during germline development. In adult tissues, it is mainly expressed in spermatogonia, the stem cells of the germline. Also expressed during meiosis in spermatocytes. Not present in late, post-meiotic stage germ cells. Expressed in fetal ovaries, while it is weakly or not expressed in mature postmeiotic oocytes, suggesting that it may be expressed in premeiotic female germ cells. Expressed at high levels only in the E-cadherin deficient cell lines. Highly expressed in lung carcinomas and mostly detected in invasive tumor cells and its expression correlates with tumor aggressiveness. {ECO:0000269|PubMed:12690449, ECO:0000269|PubMed:17047063, ECO:0000269|PubMed:18223680, ECO:0000269|PubMed:19168546, ECO:0000269|PubMed:21421998}.
