Target Name
Semaphorin-4D
Gene Name
SEMA4D
Synonyms
BB18; CD100; GR3; SEMA4D
Target Type
Clinical Trial
Disease Multiple scierosis [ICD9: 340; ICD10: G35]
Function
Cell surface receptor for PLXN1B and PLXNB2 that playsan important role in cell-cell signaling. Promotes reorganization of the actin cytoskeleton and plays a role in axonal growth cone guidance in the developing central nervous system. Regulates dendrite and axon branching and morphogenesis. Promotes the migration of cerebellar granule cells and of endothelial cells. Plays a role in the immune system; induces B-cells to aggregate and improves their viability (in vitro). Promotes signaling via SRC and PTK2B/PYK2, which then mediates activation of phosphatidylinositol 3-kinase and of the AKT1 signaling cascade. Interaction with PLXNB1 mediates activation of RHOA.
