Spermadhesin (IPR000124)

Short name: Spermadhesin

Overlapping homologous superfamilies

Family relationships



A family of mammalian sperm proteins has been characterised [PMID: 8269963, PMID: 8397818]. As shown in the following schematic representation these proteins, which have from 110 to 130 amino acid residues, contain four conserved cysteines involved in two disulphide bonds. Structurally, the spermadhesins consist of a CUB domain [PMID: 8510165].
