Glypican-3 is a protein that in humans is encoded by the GPC3 gene.^[1]^[2]^[3]^[4] The protein encoded by this gene is a member of the glypican family.

[edit] Structure and function

Cell surface heparan sulfate proteoglycans are composed of a membrane-associated protein core substituted with a variable number of heparan sulfate chains. Members of the glypican-related integral membrane proteoglycan family (GRIPS) contain a core protein anchored to the cytoplasmic membrane via a glycosyl phosphatidylinositol linkage. These proteins may play a role in the control of cell division and growth regulation.^[3]

[edit] Disease linkage

Deletion mutations in this gene are associated with Simpson-Golabi-Behmel syndrome.^[5]

[edit] Diagnostic utility

Glypican 3 immunostaining has utility for differentiating hepatocellular carcinoma (HCC) and dysplastic changes in cirrhotic livers; HCC stains with glypican 3, while liver with dysplastic changes and/or cirrhotic changes does not.^[6]
