POU3F3 Gene Summary [Human]
This gene encodes a POU-domain containing protein that functions as a transcription factor. The encoded protein recognizes an octamer sequence in the DNA of target genes. This protein may play a role in development of the nervous system. [provided by RefSeq, Apr 2015]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in human POU3F3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- Pou domain - N-terminal to homeobox domain
- RNA polymerase II transcription factor activity, sequence-specific DNA binding
- transcription regulator
- protein homodimerization
- protein domain specific binding
- protein binding
- sequence-specific DNA binding
- transcription factor activity
- homeodomain
