HUGO Symbol: SP1 Full Name: Sp1 transcription factor
Exons: 6 Introns: 5

Description:
The Sp1 gene encodes 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. There are several potential Sp1 binding sites in the γ-globin gene promoter, while mutations at these sites have been shown to enhance Sp1 binding and, thereby, Sp1-dependent promoter activity, allowing high level expression of the γ-globin genes. 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. The R218Q variant of Sp1 has been associated with elevated HbF in β-thalassaemia patients.
