Entrez ID 23203
Gene name Peptidase, mitochondrial processing subunit alpha
Gene symbol PMPCA
Synonyms (NCBI Gene)
Alpha-MPPCLA1CPD3INPP5EMAS2P-55SCAR2
Chromosome 9
Chromosome location 9q34.3
Summary The protein encoded by this gene is found in the mitochondrion, where it represents the alpha subunit of a proteolytic heterodimer. This heterodimer is responsible for cleaving the transit peptide from nuclear-encoded mitochondrial proteins. Defects in th
