PCSK1(redirected from Proprotein convertase 1)
Also found in: Acronyms, Wikipedia.
PCSK1A gene on chromosome 5q15-q21 that encodes a peptidase S8 family convertase involved in processing pairs of basic amino acid residues located on prohormones and other protein precursors (e.g., POMC, renin, enkephalin, dynorphin, somatostatin and insulin).
Defects in PCSK1 cause proprotein convertase 1 deficiency.
