POU1F1
POU class 1 homeobox 1
Pathway candidate — not linked to PFS or PSSD by any record here
Gene summary
A protein-coding gene on chromosome 3 (cell signaling and transcription factors). 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.

Protein reference (UniProt)
- Protein
Pituitary-specific positive transcription factor 1
- Function
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.
- Subcellular location
Nucleus.
- Associated conditions
Pituitary hormone deficiency, combined, 1 (CPHD1).

Why its pathway is in the library
General signaling/transcription machinery; no direct post-drug-syndrome link established for most members — included for completeness of the panel.
Written for the whole signaling & transcription family, not for POU1F1 specifically.
Mentioned in 0 corpus records
No corpus record names POU1F1 directly yet. It is in the library because it sits in a pathway the corpus tracks (Signaling & transcription).
