This gene encodes the protein core of a seminal plasma proteoglycan containing chondroitin- and heparan-sulfate chains. The protein's function is under research, though it is from the same family of glycoproteins as SPARC. It is thought its similarity to thyropin-type cysteine protease inhibitors suggests its function may be related to protease inhibition.^[6]
