Also known as: PIT1; CPHD1; GHF-1; Pit-1; POU1F1a
Summary: This gene encodes a member of the POU family of transcription factors that regulate mammalian development. The protein regulates expression of several genes involved in pituitary development and hormone expression. Mutations in this genes result in combined pituitary hormone deficiency. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

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.

See identical proteins and their annotated locations for NP_000297.1

Status: REVIEWED

Description

Transcript Variant: This variant (alpha) uses an alternate in-frame splice site in the 5' coding region, compared to variant beta, resulting in a shorter protein (isoform alpha).
