Glypican 1 (glypiated proteoglycan 1) is a 200kD, highly glycosylated member of the GPI-linked Glypican family of proteins. It is expressed by both epithelial and mesodermally-derived cells, and appears to use its proteoglycan adduct to regulate growth factor signaling and availability. Human Glypican 1 is synthesized as a 535 amino acid (aa) proprecursor that contains a 507 mature region (aa 24-530) and a 28 aa C-terminal prosegment. There are three potential splice variants. One shows an alternate start site at Met73, a second incorporates the same start site with a 65 aa substitution for aa 295-558, and a third shows a deletion of aa 184-558. Mature human Glypican 1 is 91% aa identical to mouse Glypican 1.
