POU4F2 is a member of thePOU-domain family of transcription factors. POU-domain proteins have been observed to play important roles in control of cell identity in several systems. Aclass IV POU-domain protein, POU4F2 is found in human retina exclusively within a subpopulation ofganglion cells where it may play a role in determining or maintaining the identities of a small subset ofvisual systemneurons.[supplied by OMIM][5]
