GtoPdb Ligand ID: 845

Synonyms: SDF-1β | stromal cell-derived factor-1 (SDF-1) | stromal cell-derived factor-1β
Comment: CXCL12-1α and β were the first isoforms of this chemokine identified. Both proteins contain a signal peptide sequence that medaites their secretion via the canonical intracellular secretory pathway. CXCL12 participates in a variety of processes central to homeostasis and physiology, exerting its biological effects by binding to the chemokine receptors CXCR4 and CXCR7.
