SDF-1 beta, CXCL12, rat: SDF-1α and β are stromal derived CXC chemokines, and signal through the CXCR4 receptor.
SDF-1α and β chemoattract B and T cells and have been shown to induce migration of CD34+ stem cells.
Additionally, the SDF-1 proteins exert HIV suppressive activity in cells expressing the CXCR4 receptor., UnitProt ID: Q9QZD1
