This entry includes Spermatogenesis-associated protein 6 (SPATA6) and SPATA6-like proteins. SPATA6 has similarity with the motor domain of kinesin related proteins and the Caenorhabditis elegans neural calcium sensor protein (NCS-2) []. It plays a role in linking the developing flagellum to the head during late spermiogenesis by being involved in the formation of the segmented columns and the capitulum, two major structures of the sperm connecting piece []. The function of SPATA6L is not clear.
