Pathway candidate — not linked to PFS or PSSD by any record here
Gene summary
A protein-coding gene on chromosome 6 (hpg and gonadal axis). Encodes the anterior pituitary hormone prolactin. This secreted hormone is a growth regulator for many tissues, including cells of the immune system.

Protein reference (UniProt)
- Protein
Prolactin
- Function
Prolactin acts primarily on the mammary gland by promoting lactation.
- Subcellular location
Secreted.

Why its pathway is in the library
HPG-axis signaling and steroid carrier proteins govern testosterone production and bioavailability — central to the endocrine phenotype of post-drug syndromes.
Written for the whole hpg / gonadal axis family, not for PRL specifically.
Mentioned in 0 corpus records
No corpus record names PRL directly yet. It is in the library because it sits in a pathway the corpus tracks (HPG / gonadal axis).
