NK3 Homeobox1 (NKX3-1) is a homeobox-containing transcription factor, which binds preferentially the consensus sequence 5'-TAAGT[AG]-3' and may act as a transcriptional repressor. The NKX3-1 transcription factor functions as a negative regulator of epithelial cell growth in prostate tissue. NKX3-1 has an imperative role in normal prostate development, regulating proliferation of glandular epithelium and in the formation of ducts in prostate. In addition, NKX3-1 functions as a tumor suppressor controlling prostate carcinogenesis, as shown by its ability to inhibit proliferation and invasion activities of PC-3 prostate cancer cells. Abnormal expression of NKX3-1 is linked with prostate tumor progression.

NKX3-1 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 257 amino acids (1-234 a.a) and having a molecular mass of 28.7kDa.NKX3-1 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

UniProt Protein Function:NKX3-1: Transcription factor, which binds preferentially the consensus sequence 5'-TAAGT[AG]-3' and can behave as a transcriptional repressor. Play an important role in normal prostate development, regulating proliferation of glandular epithelium and in the formation of ducts in prostate. Act as a tumor suppressor controlling prostate carcinogenesis, as shown by the ability to inhibit proliferation and invasion activities of PC-3 prostate cancer cells. Interacts with serum response factor (SRF). Interacts with SPDEF. Interacts with WDR77. Interacts with TOPORS which polyubiquitinates NKX3-1 and induces its proteasomal degradation. By androgens and, in the LNCAP cell line, by estrogens. Androgenic control may be lost in prostate cancer cells during tumor progression from an androgen-dependent to an androgen- independent phase. Highly expressed in the prostate and, at a lower level, in the testis. Belongs to the NK-3 homeobox family. 5 isoforms of the human protein are produced by alternative splicing.Protein type: Tumor suppressor; Transcription factor; DNA-bindingChromosomal Location of Human Ortholog: 8p21.2Cellular Component: intracellular; nucleusMolecular Function: androgen receptor activity; caspase activator activity; estrogen receptor activity; estrogen receptor binding; histone deacetylase binding; protein binding; protein kinase activator activity; protein self-association; sequence-specific DNA binding; transcription factor activity; transcription factor bindingBiological Process: androgen receptor signaling pathway; branching morphogenesis of a tube; caspase activation; multicellular organismal development; negative regulation of cell proliferation; negative regulation of epithelial cell proliferation; negative regulation of insulin-like growth factor receptor signaling pathway; negative regulation of mitotic cell cycle; negative regulation of transcription, DNA-dependent; positive regulation of caspase activity; positive regulation of cell division; positive regulation of cell proliferation; positive regulation of mitotic cell cycle; positive regulation of phosphoinositide 3-kinase cascade; positive regulation of protein amino acid phosphorylation; positive regulation of transcription from RNA polymerase II promoter; positive regulation of transcription, DNA-dependent; protein kinase B signaling cascade; response to testosterone stimulus; salivary gland development
UniProt Protein Details:
NCBI Summary:This gene encodes a homeobox-containing transcription factor. This transcription factor functions as a negative regulator of epithelial cell growth in prostate tissue. Aberrant expression of this gene is associated with prostate tumor progression. Alternate splicing results in multiple transcript variants of this gene. [provided by RefSeq, Jan 2012]
