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.
基因名
NKX3-1
蛋白名
Homeobox protein Nkx-3.1
亚基
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.
亚细胞定位
Nucleus.
组织特异性
Highly expressed in the prostate and, at a lower level, in the testis.
翻译后修饰
Ubiquitinated by TOPORS; monoubiquitinated at several residues and also polyubiquitinated on single residues.
相似性
Belongs to the NK-3 homeobox family.
Contains 1 homeobox DNA-binding domain.
