Specificity Protein 1/SP1 is a transcription factor that can activate or repress transcription in response to physiological and pathological stimuli. Binds with high affinity to GC-rich motifs and regulates the expression of a large number of genes involved in a variety of processes such as cell growth, apoptosis, differentiation and immune responses. Highly regulated by post-translational modifications (phosphorylations, sumoylation, proteolytic cleavage, glycosylation and acetylation). Binds also the PDGFR- alpha G-box promoter. May have a role in modulating the cellular response to DNA damage. Implicated in chromatin remodeling. In complex with ATF7IP, maintains telomerase activity in cancer cells by inducing TERT and TERC gene expression. [UniProt]
Titration of the SP1 antibody may be required due to differences in protocols and secondary/substrate sensitivity.
This SP1 antibody was produced from a mouse immunized with recombinant Specificity Protein 1.
Aliquot the SP1 antibody and store frozen at -20oC or colder. Avoid repeated freeze-thaw cycles.
