CC -!- FUNCTION: Transcription factor involved in the specification of the
CC lactotrope, somatotrope, and thyrotrope phenotypes in the developing
CC anterior pituitary. Activates growth hormone and prolactin genes.
CC Specifically binds to the consensus sequence 5'-TAAAT-3'.
CC {ECO:0000250|UniProtKB:P28069}.
CC -!- SUBUNIT: Interacts with PITX1. Interacts with LHX3. Interacts with
CC ELK1. {ECO:0000250|UniProtKB:P28069}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P28069}.
CC -!- DOMAIN: The 9aaTAD motif is a transactivation domain present in a large
CC number of yeast and animal transcription factors.
CC {ECO:0000250|UniProtKB:P28069}.
CC -!- SIMILARITY: Belongs to the POU transcription factor family. Class-1
CC subfamily. {ECO:0000305}.
