Biochemical and Physiological Mechanisms
Receptor for the C-X-C chemokine CXCL12/SDF-1 that transduces a signal by increasing intracellular calcium ions levels and enhancing MAPK1/MAPK3 activation. Acts as a receptor for extracellular ubiquitin; leading to enhance intracellular calcium ions and

Recombinant Human CXCR4 Protein (rp214408) - SDS-PAGE 3 μg/lane of Recombinant Human CXCR4 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 30.9 kDa under reducing conditions and 28.9 & 30.9 & 31.8 kDa under non-reducing conditions. The CXCR4 protein exhibits multiple bands under both reducing (R) and non-reducing (NR) conditions. In R conditions, the band multiplicity likely stems from limited post-translational modification (PTM) variability (e.g., partial glycosylation or sulfation). Under NR conditions, the additional bands may arise from conformational heterogeneity, such as disulfide bond-mediated structural variations or oligomerization states stabilized in the absence of reducing agents (PubMed:10089882, 10756055).
