SPANX family member N1 is a protein that in humans is encoded by the SPANXN1 gene.
[1]
Function
This gene represents one of several duplicated family members that are located on chromosome X. This gene family encodes proteins that play a role in spermiogenesis. These proteins represent a specific subgroup of cancer/testis-associated antigens, and they may be candidates for tumor vaccines. This family member belongs to a subgroup of related genes that are present in all primates and rats and mice, and thus, it represents one of the ancestral family members.
