CATEGORY

transcription factor

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus

basic FUNCTION	playing a role in fetal skin development and cutaneous regeneration
	may play an important role in tumors arising from endocrine-responsive organs
	functions as an AR repressor to modulate the complex AR signaling and subsequent growth regulation of prostate cancer cells
	with the androgen receptor (AR), plays a critical role in the normal development of the prostate gland
	homeobox transcription factor gene that is important in prostate development

CELLULAR PROCESS

nucleotide, transcription

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

INTERACTION

DNA

RNA

small molecule

protein

interacts with the DNA-binding domain of AR and inhibits the transcription of genes that contain an androgen-response element (ARE)
