Glypican-1 is a protein that in humans is encoded by the GPC1 gene.[1][2]
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.[2]
Interactions
Glypican 1 has been shown to interact with SLIT2.[3]
Clinical significance
This protein is involved in the misfolding of normal prion proteins in the cell membrane to the infectious prion form.[4]
In 2015 it was reported that the presence of this protein in exosomes in patients' blood is able to detect early pancreatic cancer with absolute specificity and sensitivity.[5] However this conclusion is disputed.[6] and in more recent overviews of potential markers for pancreatic cancer, Glypican 1 is not mentioned.[7][8]
