Glypican 2 (GPC2), also known cerebroglycan, is a protein which in humans is encoded by the GPC2 gene.[5][6]

Function[edit]

Cerebroglycan is a glycophosphatidylinositol-linked integral membrane heparan sulfate proteoglycan found in the developing nervous system. Cerebroglycan participates in cell adhesion and is thought to regulate the growth and guidance of axons.[7] Cerebroglycan has especially high affinity for laminin-1.[8]

Implications in cancer[edit]

GPC2 has been suggested as a therapeutic target in neuroblastoma.[9][10] GPC2 is highly expressed in about half of neuroblastoma cases and that high GPC2 expression correlates with poor overall survival.[9] GPC2 silencing inactivates Wnt/β-catenin signaling and reduces the expression of N-Myc, an oncogenic driver of neuroblastoma tumorigenesis.[9] Immunotoxins and chimeric antigen receptor (CAR) T cells targeting GPC2 inhibit neuroblastoma growth in mouse models.[9] A GPC3 specific antibody drug conjugate (ADC) can also inhibit neuroblastoma cell proliferation.[10]
