Informations générales

PQBP1 (Polyglutamine-binding protein 1) is also named as NPW38 and JM26. PQBP1 senses extrinsic tau 3R/4R proteins by direct interaction and triggers an innate immune response by activating a cyclic GMP-AMP synthase (cGAS)-Stimulator of interferon genes (STING) pathway (PMID: 34782623).  PQBP1 is abundantly expressed in the central nervous system during development. PQBP1 is a component of the precatalytic spliceosome (B complex) that is involved in splicing. PQBP1 was predominantly localized in the cell nucleus. PQBP1 is overexpressed in various cancer types including breast cancer, colon cancer, and glioblastoma (PMID: 38342602).
