In silico analysis predicted that the TEX55 protein is predominantly localized in the nucleus and contains a putative anchoring domain similar to that found in cAMP‐dependent type II protein kinase, suggesting its involvement in nuclear signaling pathways critical for germ cell development. Expression studies further revealed that TEX55 is expressed at low levels in early testicular development (e.g., 21-day-old mouse testes) and exhibits a gradual increase as the testes mature, correlating with the progression of spermatogenesis. Notably, the absence of TEX55 expression in human conditions such as cryptorchidism and Sertoli-cell-only syndrome underscores its likely importance in normal testicular function and fertility."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Zhendong Yu, Bo Wu, Aifa Tang, et al.
