Gene Information

human ... CXCL12((6387)

Stromal Cell-Derived Factor 1α (SDF-1α) or pre-B Cell Growth Stimulation Factor (PBSF) is an 8 kDa chemokine peptide. SDF-1 was identified using signal sequence trap cloning. With this method, cDNAs have been cloned using mouse and human stromal cell lines. This cytokine is widely accepted as a CXC chemokine of the intercrine-macrophage inflammatory protein superfamily. The gene has been mapped to chromosome 10q and is encoded by 4 exons. Expression of the human SDF1 gene is abundant in the pancreas, spleen, ovary, and small intestine. The presence of a GC-rich sequence and the lack of a TATA box in the 5∅-flanking region of the gene are consistent with ubiquitous expression.
