Inner mitochondrial membrane peptidase subunit 1 (IMMP1L)

Inner mitochondrial membrane peptidase subunit 1 (IMMP1L) is an enzyme located in the inner membrane of mitochondria. IMMP1L acts as a catalytic subunit of the mitochondrial inner membrane peptidase (IMP) complex, which is responsible for the proteolytic cleavage of mitochondrial targeting sequences from precursor proteins imported into the mitochondrial intermembrane space. This processing is critical for the maturation and function of various nuclear-encoded mitochondrial proteins. The IMP complex in humans comprises two catalytic subunits, IMMP1L and IMMP2L. IMMP1L is highly conserved and structurally related to yeast Imp1. While IMMP1L’s biochemical role is presumed to be vital for mitochondrial protein maturation, current evidence does not identify it as a direct disease gene or drug target. Deletions encompassing IMMP1L have been observed in chromosomal rearrangements linked to ocular developmental disorders, but pathogenic effects are primarily attributed to regulatory disruption of neighboring critical genes such as PAX6.
