The function of ENSG00000136449 (MYCBPAP, MYCBP associated protein) is as follows. Plays a crucial role in centrosome-nuclear envelope docking during spermiogenesis, a key step for anchoring the centrosome to the nucleus that is essential for proper sperm flagellum biogenesis. Also required for acrosome biogenesis, manchette organization, and spermatid head morphogenesis, contributing to the complete and functional assembly of the sperm flagellum. .
