SPATC1 encodes the human gene, Spermatogenesis and centriole associated 1. It may also be known as: Speriolin; Spermatogenesis-associated protein 15; Spermatogenic cell-specific Cdc20-binding protein; Spermatogenesis and centriole-associated protein 1; SPATA15. The encoded protein has an amino acid length of 591 and a mass of 62.4 kDa. Other isoforms may exist. SPATC1 is a member of the Speriolin family. Homologs of this gene exist in other organisms, including: Mouse, Rat.
