Entrez Gene Summary:
For background information on chemokines, see CXCL11 (SCYB11; MIM 604852). Stromal cell-derived factors 1-alpha and 1-beta are small cytokines that belong to the intercrine family, members of which activate leukocytes and are often induced by proinflammatory stimuli such as lipopolysaccharide, TNF (see MIM 191160), or IL1 (see MIM 147760). The intercrines are characterized by the presence of 4 conserved cysteines which form 2 disulfide bonds. They can be classified into 2 subfamilies. In the CC subfamily, which includes beta chemokine, the cysteine residues are adjacent to each other. In the CXC subfamily, which includes alpha chemokine, they are separated by an intervening amino acid. The SDF1 proteins belong to the latter group.[supplied by OMIM]
UniProt Summary:
FUNCTION: SwissProt: P48061 # Chemoattractant active on T-lymphocytes, monocytes, but not neutrophils. SDF-1-beta(3-72) and SDF-1-alpha(3-67) show a reduced chemotactic activity. Binding to cell surface proteoglycans seems to inhibit formation of SDF-1-alpha(3-67) and thus to preserve activity on local sites.
SIZE: 93 amino acids; 10666 Da
SUBCELLULAR LOCATION: Secreted.
PTM: Processed forms SDF-1-beta(3-72) and SDF-1-alpha(3-67) are produced after secretion by proteolytic cleavage of isoforms Beta and Alpha, respectively. The N-terminal processing is probably achieved by DPP4. Isoform Alpha is first cleaved at the C-terminus to yield a SDF-1-alpha(1-67) intermediate before being processsed at the N-terminus. The C-terminal processing of isoform Alpha is reduced by binding to heparin and, probably, cell surface proteoglycans.
SIMILARITY: SwissProt: P48061 ## Belongs to the intercrine alpha (chemokine CxC) family.

Determined by its ability to chemoattract human peripheral T cells activated with PHA and IL-2 using a concentration range of 20.0-80.0 ng/mL.
Storage Conditions:
The lyophilized powder, though stable at room temperature, is best stored desiccated below 0°C. Reconstitute in water to a concentration of 0.1-1 mg/mL. It is recommended that further dilutions be made into buffer containing carrier protein or medium containing serum. Reconstituted SDF1alpha should be stored at 4°C or in undiluted aliquots at -20°C for up to 6 months.
