Pituitary-specific positive transcription factor 1
Gene
POU1F1, GHF1, PIT1
Organism
Macaca mulatta (Rhesus macaque)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

Functioni

Transcription factor involved in the specification of the lactotrope, somatotrope, and thyrotrope phenotypes in the developing anterior pituitary. Activates growth hormone and prolactin genes. Specifically binds to the consensus sequence 5'-TAAAT-3' By similarity.
