Official Full Name Sp1 transcription factor
Background The protein encoded by this gene is a zinc finger transcription factor that binds to GC-rich motifs of many promoters. The encoded protein is involved in many cellular processes, including cell differentiation, cell growth, apoptosis, immune responses, response to DNA damage, and chromatin remodeling. Post-translational modifications such as phosphorylation, acetylation, glycosylation, and proteolytic processing significantly affect the activity of this protein, which can be an activator or a repressor. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

    SP1 has several biochemical functions, for example, DNA binding, HMG box domain binding, RNA polymerase II core promoter proximal region sequence-specific DNA binding. Some of the functions are cooperated with other proteins, some of the functions could acted by SP1 itself. We selected most functions SP1 had, and list some proteins which have the same functions with SP1. You can find most of the proteins on our site.
