Sp3 transcription factor, also known as SP3, refers to both a protein and the gene it is encoded by.
This gene belongs to a family of Sp1 related genes that encode transcription factors that regulate transcription by binding to consensus GC- and GT-box regulatory elements in target genes. This protein contains a zinc finger DNA-binding domain and several transactivation domains, and has been reported to function as a bifunctional transcription factor that either stimulates or represses the transcription of numerous genes. Transcript variants encoding different isoforms have been described for this gene, and one has been reported to initiate translation from a non-AUG (AUA) start codon. Additional isoforms, resulting from the use of alternate downstream translation initiation sites, have also been noted. [5]
Sp3 transcription factor has been shown to interact with Histone deacetylase 2, [6] [7] PIAS1, [8] E2F1 [9] and GABPA. [10]

Transcription factor E2F1 is a protein that in humans is encoded by the E2F1 gene.
Histone deacetylase 3 is an enzyme encoded by the HDAC3 gene in both humans and mice.
POU domain, class 2, transcription factor 1 is a protein that in humans is encoded by the POU2F1 gene.
Nuclear transcription factor Y subunit alpha is a protein that in humans is encoded by the NFYA gene.
Nuclear transcription factor Y subunit beta is a protein that in humans is encoded by the NFYB gene.
Myocyte-specific enhancer factor 2A is a protein that in humans is encoded by the MEF2A gene. MEF2A is a transcription factor in the Mef2 family. In humans it is located on chromosome 15q26. Certain mutations in MEF2A cause an autosomal dominant form of coronary artery disease and myocardial infarction.
