Target Details

Target: CXCL12 (Chemokine (C-X-C Motif) Ligand 12 (CXCL12))

Alternative Name: CXCL12/SDF-1alpha

Background: Stromal-Cell Derived Factor-1alpha (SDF-1alpha) (CXCL12) attracts lymphocytes and plays important roles in embryogenesis and angiogenesis with implications in tumor metastasis. By binding to CXCR4, one of the co-receptors for HIV viral entry, SDF-1alpha can suppress HIV. Besides CXCR4, SDF-1alpha also binds to the “decoy” receptor CXCR7, and activates the downstream beta-arrestin- rather than G protein-mediated signaling pathway.

Molecular Weight: 10.381 kDa

UniProt: P48061

Pathways: Regulation of Cell Size, CXCR4-mediated Signaling Events, Negative Regulation of intrinsic apoptotic Signaling
