Protein
POU domain protein 2, isoform B
Gene
pdm2, dim, OCT2, pdm-2, POU-28, CG12287
Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at transcript leveli

Functioni

DNA-binding regulatory protein implicated in early development. Involved in neuronal cell fate decision. May act as an octamer-dependent activator of transcription. Could also play an early role in specific ectodermal cells, and a subsequent role in the embryonic nervous system.4 Publications
