Tissue Specificity[Isoform 1]: Strongly expressed in the liver.;
[Isoform 7]: Widely expressed, but strongly expressed in all spermatogenesis-related tissues, including the testis, the epithelium of cauda and the corpus epididymis, as well as the spermatid and mature sperm. Also expressed in Leydig cells. {ECO:0000269|PubMed:15863901, ECO:0000269|PubMed:32161152}.
