Entrez Gene summary for SP1 Gene:

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)

GeneCards Summary for SP1 Gene:

SP1 (Sp1 transcription factor) is a protein-coding gene. Diseases associated with SP1 include cerebrotendinous xanthomatosis, and erythropoietic protoporphyria, and among its related super-pathways are Activation of Gene Expression by SREBP (SREBF) and Prolactin Signaling Pathway. GO annotations related to this gene include sequence-specific DNA binding and sequence-specific DNA binding transcription factor activity. An important paralog of this gene is KLF1.

UniProtKB/Swiss-Prot: SP1_HUMAN, P08047

Function: 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. Plays a role in the recruitment of

SMARCA4/BRG1 on the c-FOS promoter. Plays an essential role in the regulation of FE65 gene expression. In complex

with ATF7IP, maintains telomerase activity in cancer cells by inducing TERT and TERC gene expression

About This Section

UniProtKB/Swiss-Prot: SP1_HUMAN, P08047 (See protein sequence)

Recommended Name: Transcription factor Sp1

Size: 785 amino acids; 80693 Da

Subunit: Interacts with ATF7IP, ATF7IP2, BAHD1, POGZ, HCFC1, AATF and PHC2. Interacts with varicella-zoster virus

IE62 protein. Interacts with HIV-1 Vpr; the interaction is inhibited by SP1 O-glycosylation. Interacts with SV40

VP2/3 proteins. Interacts with SV40 major capsid protein VP1; this interaction leads to a cooperativity between

the 2 proteins in DNA binding. Interacts with HLTF; the interaction may be required for basal transcriptional

activity of HLTF. Interacts (deacetylated form) with EP300; the interaction enhances gene expression. Interacts

with HDAC1 and JUN. Interacts with ELF1; the interaction is inhibited by glycosylation of SP1. Interaction with

NFYA; the interaction is inhibited by glycosylation of SP1. Interacts with SMARCA4/BRG1 (By similarity).

Interacts with ATF7IP and TBP. Interacts with MEIS2 isoform 4 and PBX1 isoform PBX1a. Interacts with EGR1

Subcellular location: Nucleus. Cytoplasm. Note=Nuclear location is governed by glycosylated/phosphorylated states.

Insulin promotes nuclear location, while glucagon favors cytoplasmic location

Miscellaneous: In the hepatoma cell line Hep-G2, SP1 precursor mRNA may undergo homotype trans-splicing leading to

the duplication of exons 2 and 3

Post-translational modifications:

UniProtKB: Phosphorylated on multiple serine and threonine residues. Phosphorylation is coupled to ubiquitination,

sumoylation and proteolytic processing. Phosphorylation on Ser-59 enhances proteolytic cleavage. Phosphorylation

on Ser-7 enhances ubiquitination and protein degradation. Hyperphosphorylation on Ser-101 in response to DNA

damage has no effect on transcriptional activity. MAPK1/MAPK3-mediated phosphorylation on Thr-453 and Thr-739

enhances VEGF transcription but, represses FGF2-triggered PDGFR-alpha transcription. Also implicated in the

repression of RECK by ERBB2. Hyperphosphorylated on Thr-278 and Thr-739 during mitosis by MAPK8 shielding SP1

from degradation by the ubiquitin-dependent pathway. Phosphorylated in the zinc-finger domain by

calmodulin-activated PKCzeta. Phosphorylation on Ser-641 by PKCzeta is critical for TSA-activated LHR gene

expression through release of its repressor, p107. Phosphorylation on Thr-668, Ser-670 and Thr-681 is stimulated

by angiotensin II via the AT1 receptor inducing increased binding to the PDGF-D promoter. This phosphorylation is

increased in injured artey wall. Ser-59 and Thr-681 can both be dephosphorylated by PP2A during cell-cycle

interphase. Dephosphorylation on Ser-59 leads to increased chromatin association during interphase and increases

the transcriptional activity. On insulin stimulation, sequentially glycosylated and phosphorylated on several

C-terminal serine and threonine residues

UniProtKB: Acetylated. Acetylation/deacetylation events affect transcriptional activity. Deacetylation leads to an increase

in the expression the 12(s)-lipooxygenase gene though recruitment of p300 to the promoter

UniProtKB: Ubiquitinated. Ubiquitination occurs on the C-terminal proteolytically-cleaved peptide and is triggered by

phosphorylation

UniProtKB: Sumoylated with SUMO1. Sumoylation modulates proteolytic cleavage of the N-terminal repressor domain. Sumoylation

levels are attenuated during tumorigenesis. Phosphorylation mediates SP1 desumoylation

UniProtKB: Proteolytic cleavage in the N-terminal repressor domain is prevented by sumoylation. The C-terminal cleaved

product is susceptible to degradation

UniProtKB: O-glycosylated; Contains 8 N-acetylglucosamine side chains. Levels are controlled by insulin and the SP1

phosphorylation states. Insulin-mediated O-glycosylation locates SP1 to the nucleus, where it is sequentially

deglycosylated and phosphorylated. O-glycosylation affects transcriptional activity through disrupting the

interaction with a number of transcription factors including ELF1 and NFYA. Also inhibits interaction with the

HIV1 promoter. Inhibited by peroxisomome proliferator receptor gamma (PPARgamma)
