General description

Sp1 (Simian virus 40 protein-1) is a ubiquitous sequence specific nuclear transcription factor that recognizes GGGGCGGGGC and related sequences (GC boxes) on numerous viral and cellular genes. The sequence specificity of DNA binding is conferred by three c-terminal Cys2His2-type zinc -fingers and its affinity is regulated by a different region. Sp1 is an abundant phosphorylated and O-glycosylated protein that is expressed in most cells in levels dependent on cell type and developmental stage. It is a member of a family comprising Sp1, Sp2, Sp3, Sp4 and at least twelve additional Sp1 like members.


synthetic peptide of human Sp1, amino acids 436-454 with N-terminally added lysine, conjugated to KLH.


Anti-Sp1 antibody produced in rabbit has been used in western blotting and immunoprecipitation.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide
