Protein function (UniProt)

Mitochondrial-processing peptidase subunit alpha

Substrate recognition and binding subunit of the essential mitochondrial processing protease (MPP), which cleaves the mitochondrial sequence off newly imported precursors proteins

Curated MONDO disease pages that list PMPCA among their top associated genes.
