NCBI and Uniprot Product Information
NCBI Description
This gene encodes a phosphoprotein containing six characteristic repeat motifs. The encoded protein binds to the initiator element (Inr) and E-box element in promoters and functions as a regulator of transcription. This locus, along with several other neighboring genes, is deleted in Williams-Beuren syndrome. There are many closely related genes and pseudogenes for this gene on chromosome 7. This gene also has pseudogenes on chromosomes 9, 13, and 21. Alternatively spliced transcript variants encoding multiple isoforms have been observed. [provided by RefSeq, Jul 2013]
Uniprot Description
Function: Interacts with the basal transcription machinery by coordinating the formation of a multiprotein complex at the C-FOS promoter, and linking specific signal responsive activator complexes. Promotes the formation of stable high-order complexes of SRF and PHOX1 and interacts cooperatively with PHOX1 to promote serum-inducible transcription of a reporter gene deriven by the C-FOS serum response element (SRE). Acts as a coregulator for USF1 by binding independently two promoter elements, a pyrimidine-rich initiator (Inr) and an upstream E-box. Required for the formation of functional ARID3A DNA-binding complexes and for activation of immunoglobulin heavy-chain transcription upon B-lymphocyte activation. Ref.8 Ref.9 Ref.13
Subunit structure: Homodimer
Potential. Interacts with SRF and PHOX1. Binds a pyrimidine-rich initiator (Inr) and a recognition site (E-box) for upstream stimulatory factor 1 (USF1). Associates with the PH domain of Bruton's tyrosine kinase (BTK). May be a component of a BHC histone deacetylase complex that contains HDAC1, HDAC2, HMG20B/BRAF35, KDM1A, RCOR1/CoREST, PHF21A/BHC80, ZMYM2, ZNF217, ZMYM3, GSE1 and GTF2I. Interacts with BTK and ARID3A. Interacts with isoform beta of PRKG1. Ref.8 Ref.9 Ref.10 Ref.13
Subcellular location: Cytoplasm. Nucleus. Note: Colocalizes with BTK in the cytoplasm. Ref.8
Tissue specificity: Ubiquitous. Isoform 1 is strongly expressed in fetal brain, weakly in adult brain, muscle, and lymphoblasts and is almost undetectable in other adult tissues, while the other isoforms are equally expressed in all adult tissues.
Post-translational modification: Transiently phosphorylated on tyrosine residues by BTK in response to B-cell receptor stimulation. Phosphorylation on Tyr-248 and Tyr-398, and perhaps, on Tyr-503 contributes to BTK-mediated transcriptional activation. Ref.8 Ref.9 Ref.10 Ref.13Sumoylated. Ref.11
Involvement in disease: GTF2I is located in the Williams-Beuren syndrome (WBS) critical region. WBS results from a hemizygous deletion of several genes on chromosome 7q11.23, thought to arise as a consequence of unequal crossing over between highly homologous low-copy repeat sequences flanking the deleted region. Haploinsufficiency of GTF2I may be the cause of certain cardiovascular and musculo-skeletal abnormalities observed in the disease.
Sequence similarities: Belongs to the TFII-I family.Contains 6 GTF2I-like repeats.

Product Notes
The GTF2I gtf2i (Catalog #AAA647932) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The GTF2I, NT (GTF2I, BAP135, WBSCR6, General transcription factor II-I, Bruton tyrosine kinase-associated protein 135, SRF-Phox1-interacting protein, Williams-Beuren syndrome chromosomal region 6 protein) reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's GTF2I can be used in a range of immunoassay formats including, but not limited to, ELISA (EL/EIA), Western Blot (WB). Suitable for use in Western Blot, ELISA Dilution: ELISA: 1:1,000 Western Blot: 1:100-500. Researchers should empirically determine the suitability of the GTF2I gtf2i for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "GTF2I, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
