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
POU3F3 [ENSP00000355001]
 
POU class 3 homeobox 3; Transcription factor that acts synergistically with SOX11 and SOX4. Plays a role in neuronal development. Is implicated in an enhancer activity at the embryonic met- mesencephalic junction; the enhancer element contains the octamer motif (5'-ATTTGCAT-3') (By similarity)
