SPACA6 ectodomain structure reveals a conserved superfamily of gamete fusion-associated proteins
Abstract
The crystal structure of sperm-expressed surface protein SPACA6 shows similarities to IZUMO1 though their functions are not redundant. Structural homology search in the AlphaFold human proteome and sequence search suggest a superfamily of mammalian gamete fusion-associated proteins.
