PARL (Presenilin-associated rhomboid-like) is a mitochondrial intramembrane serine protease belonging to the rhomboid family, which is evolutionarily conserved and plays critical roles in regulating mitochondrial dynamics, quality control, and apoptosis. Discovered in 2001. PARL is embedded in the inner mitochondrial membrane (IMM) and undergoes autoproteolytic processing to generate its active form. Structurally, it contains six transmembrane domains and a catalytic serine-histidine dyad essential for its enzymatic activity.
PARL gained prominence due to its involvement in mitochondrial homeostasis. It cleaves substrates like PHB2 (prohibitin-2) and FAM210A, which regulate mitochondrial morphology, cristae structure, and mitophagy. Notably, PARL processes PINK1 (PTEN-induced kinase 1), a key protein in Parkinson’s disease pathogenesis. Under normal conditions, PARL-mediated cleavage of PINK1 limits its accumulation on the mitochondrial surface. During stress, PINK1 stabilization activates Parkin, triggering mitophagy to eliminate damaged mitochondria. Dysregulation of PARL has been linked to neurodegenerative diseases, metabolic disorders, and cancer.
Recombinant PARL proteins are engineered using expression systems (e.g., E. coli, mammalian cells) to study its enzymatic mechanisms, substrate interactions, and structural features. These tools enable drug discovery targeting mitochondrial dysfunction. Research on PARL also explores its role in apoptosis via OPA1 processing and its interplay with BCL-2 family proteins. Despite progress, challenges remain in fully elucidating its substrate network and pathophysiological relevance. Overall, PARL represents a pivotal therapeutic target for mitochondrial-related diseases, with recombinant studies driving mechanistic and translational advancements.
