ABCC1
ATP binding cassette subfamily C member 1 (ABCC1 blood group)
Named by Dr Will Powers — at family level only
Gene summary
A protein-coding gene on chromosome 16 (drug and xenobiotic transporters). The protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra-and intra-cellular membranes.

ATP-binding cassette sub-family C member 1
- Function (excerpt)
ATP-dependent transporter of the ATP-binding cassette (ABC) family that hydrolyzes ATP to enable the active transport of organic anions conjugated with glutathione, glucuronate or sulfate. Operates at the plasma membrane where it mediates the efflux of substrates from the cytoplasm into the extracellular space. The rate of transport is in some way coupled to the reduced glutathione (GSH) intracellular levels. Mediates the systemic release of glutathione-conjugated leukotriene C4 (LTC4) from myeloid cells such as mast cells, as part of the inflammatory response. Exports S-geranylgeranyl-glutathione (GGG) in lymphoid cells and stromal compartments of lymphoid organs. ABCC1 (via extracellular transport) with GGT5 (via GGG catabolism) establish GGG gradients within lymphoid tissues to position P2RY8-positive lymphocytes at germinal centers in lymphoid follicles and restrict their chemotactic transmigration from blood vessels to the bone marrow parenchyma (By similarity).

Why its pathway is in the library
Transporters set systemic exposure to finasteride/SSRIs and clear conjugated steroid metabolites — directly relevant to both drug pharmacokinetics and Powers' clearance-centered PFS mechanism.
Written for the whole drug transporters family, not for ABCC1 specifically.
Powers’ note (his unpublished theorizing)
Powers named the ABCC transporter family (2026 summit interview, unpublished) as intracellular transporter genes implicated in metabolite clearance in his experimentally verifiable mechanism; individual ABCC members not separately named.
Mentioned in 0 corpus records
No corpus record names ABCC1 directly yet. It is in the library because it sits in a pathway the corpus tracks (Drug transporters).
