POU3F4 [ENSP00000362296]
POU class 3 homeobox 4; Probable transcription factor which exert its primary action widely during early neural development and in a very limited set of neurons in the mature brain
POU3F2 [ENSP00000329170]
POU class 3 homeobox 2; Transcription factor that binds preferentially to the recognition sequence which consists of two distinct half-sites, ('GCAT') and ('TAAT'), separated by a nonconserved spacer region of 0, 2, or 3 nucleotides. Positively regulates the genes under the control of corticotropin-releasing hormone (CRH) and CRH II promoters (By similarity)
