[5][6] 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.
