Cat.No. 5795 - ATI 2341 | Met-Gly-Tyr-Gln-Lys-Lys-Leu-Arg-Ser-Met-Thr-Asp-Lys-Tyr-Arg-Leu | CAS No. 1337878-62-2
Description: CXCR4 allosteric agonist

Biological Activity

CXCR4 allosteric agonist (EC50 = 194 nM). Induces chemotaxis in CXCR4-expressing cells in vitro. Mobilizes polymorphonuclear neutrophils (PMNs) and hematopoietic stem and progenitor cells (HSPCs) from bone marrow niche in vivo. Exhibits biased signaling towards Gi proteins over G13 and β-arrestin.
