Protein

POU domain, class 3, transcription factor 3

Gene

Pou3f3

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

Transcription factor that acts synergistically with SOX11 and SOX4 (By similarity). 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 similarity3 Publications

Neonatal death at least 36 hours postpartum. Loss of both Pou3f3 and Pou3f2 leads to abnormal formation of the neocortex with dramatically reduced production of layer IV-II neurons and defective migration of neurons.2 Publications
