GHF-1 Transcription factor involved in the specification of the lactotrope, somatotrope, and thyrotrope phenotypes in the developing anterior pituitary. Specifically binds to the consensus sequence 5'-TAAAT-3'. Activates growth hormone and prolactin genes. Belongs to the POU transcription factor family. Class-1 subfamily. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
