pS346/pS347-CXCR4 ( phospho-CXC Chemokine Receptor 4 Polyclonal Antibody )

Overview
- Serine346/serine347 (S346/S347) is a major phosphorylation site of the CXCR4 receptor. The pS346/pS347-CXCR4 antibody detects phosphorylation in response to agonists and after PKC activation. S346/S347 phosphorylation is a key regulator of CXCR4 desensitization, β-arrestin recruitment and internalization.
