ID Q80UU9; PN Membrane-associated progesterone receptor component 2; GN Pgrmc2; OS 10090; SL Nucleus Position: SL-0178; SL Comments: Membrane {ECO:0000305}; Single-pass membrane protein {ECO:0000305}. Nucleus envelope {ECO:0000250|UniProtKB:O15173}. Endoplasmic reticulum {ECO:0000250|UniProtKB:O15173}. DR UNIPROT: Q80UU9; DR Pfam: PF00173; DE Function: Required for the maintenance of uterine histoarchitecture and normal female reproductive lifespan (PubMed:28005395). May serve as a universal non-classical progesterone receptor in the uterus (Probable). Intracellular heme chaperone required for delivery of labile, or signaling heme, to the nucleus. Plays a role in adipocyte function and systemic glucose homeostasis. In brown fat, which has a high demand for heme, delivery of labile heme in the nucleus regulates the activity of heme-responsive transcriptional repressors such as NR1D1 and BACH1 (PubMed:31748741). {ECO:0000269|PubMed:28005395, ECO:0000269|PubMed:31748741, ECO:0000305|PubMed:28005395}.
