?





		Synonyms :
Stromal-Cell Derived Factor-1, CXCL12, PBSF



		Description :
SDF-1 alpha and beta are stromal derived CXC chemokines, and signal through the CXCR4 receptor.  SDF-1alpha and beta 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.  Recombinant human SDF-1beta is an 8.5 kDa protein containing 72 amino acid residues.
