Sperm protein associated with the nucleus, X-linked, family member C (SPANX-C) is a protein of unknown function that is expressed in human testis, sperm, and multiple types of cancers. SPANX-C is a human lineage specific copy of the SPANX gene family and has undergone positive selection. The implications of these changes are not understood but could have impacted human reproduction.
