Title: The 26-amino acid beta-motif of the Pit-1beta transcription factor is a dominant and independent repressor domain.
In the embryonic period, PROP1 coexists transiently with PIT1, which is the anterior pituitary-specific factor and is a target of PROP1, but not any hormones.
Title: PROP1 coexists with SOX2 and induces PIT1-commitment cells.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
