Human Gene NKX3-1 (ENST00000523261.1) Description and Page Index
  Description: Homo sapiens NK3 homeobox 1 (NKX3-1), transcript variant 2, mRNA. (from RefSeq NM_001256339)
RefSeq Summary (NM_001256339): 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].

  ID: NKX31_HUMAN
DESCRIPTION: RecName: Full=Homeobox protein Nkx-3.1; AltName: Full=Homeobox protein NK-3 homolog A;
FUNCTION: Transcription factor, which binds preferentially the consensus sequence 5'-TAAGT[AG]-3' and can behave as a transcriptional repressor. Plays an important role in normal prostate development, regulating proliferation of glandular epithelium and in the formation of ducts in prostate. Acts as a tumor suppressor controlling prostate carcinogenesis, as shown by the ability to inhibit proliferation and invasion activities of PC-3 prostate cancer cells.
SUBUNIT: Interacts with serum response factor (SRF) (By similarity). Interacts with SPDEF. Interacts with WDR77. Interacts with TOPORS which polyubiquitinates NKX3-1 and induces its proteasomal degradation.
INTERACTION: P11387:TOP1; NbExp=6; IntAct=EBI-1385894, EBI-876302;
SUBCELLULAR LOCATION: Nucleus.
TISSUE SPECIFICITY: Highly expressed in the prostate and, at a lower level, in the testis.
INDUCTION: 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.
PTM: Ubiquitinated by TOPORS; monoubiquitinated at several residues and also polyubiquitinated on single residues.
SIMILARITY: Belongs to the NK-3 homeobox family.
SIMILARITY: Contains 1 homeobox DNA-binding domain.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
