IMMP1L (Inner Mitochondrial Membrane Peptidase Subunit 1) is a Protein Coding gene. Among its related pathways are Protein export. The mitochondrial inner membrane peptidase (IMP) complex generates mature, active proteins in the mitochondrial intermembrane space by proteolytically removing the mitochondrial targeting presequence of nuclear-encoded proteins. IMP1 and IMP2 are the catalytic subunits of the IMP complex.
