YME1L1 (YME1 Like 1 ATPase) is a human homolog of the yeast mitochondrial escape 1 protein, belonging to the AAA+ (ATPases Associated with diverse cellular Activities) protease family. It plays a critical role in mitochondrial quality control by regulating proteostasis, dynamics, and membrane architecture. Localized to the inner mitochondrial membrane, YME1L1 functions as an ATP-dependent metalloprotease that cleaves specific substrates involved in mitochondrial fusion, cristae morphology, and apoptosis.
Structurally, it contains an N-terminal transmembrane domain and a C-terminal AAA+ ATPase module. YME1L1 participates in maintaining mitochondrial proteostasis by degrading misfolded proteins and processing key regulators like OPA1 (involved in mitochondrial fusion) and PARL (a rhomboid protease). Its activity links mitochondrial bioenergetics to structural dynamics, influencing cellular responses to metabolic stress.
Recombinant YME1L1 is produced via heterologous expression systems (e.g., E. coli or mammalian cells) for biochemical studies, enabling research into its enzymatic mechanisms and substrate specificity. Dysregulation of YME1L1 is associated with neurodegenerative disorders, cancer, and metabolic syndromes, making it a potential therapeutic target. Studies using recombinant proteins have elucidated its role in mitochondrial homeostasis and disease pathways, aiding drug discovery for mitochondrial dysfunction-related conditions.
