RNPEPL1 (arginine/leucine aminopeptidase-like 1) is a member of the M1 zinc metalloprotease family, known for its conserved catalytic domain that facilitates aminopeptidase activity. While its exact biological role remains under investigation, it shares structural homology with other aminopeptidases involved in peptide processing, particularly those hydrolyzing N-terminal arginine or leucine residues. The protein is encoded by the *RNPEPL1* gene, located on human chromosome 2. and is ubiquitously expressed across tissues, with higher levels observed in the liver, kidney, and brain.
Biochemical studies suggest RNPEPL1 may participate in protein turnover, antigen processing, or bioactive peptide regulation, though its substrate specificity and physiological partners are not fully characterized. Unlike its well-studied paralog, endoplasmic reticulum aminopeptidase 1 (ERAP1), RNPEPL1 lacks a transmembrane domain and is primarily cytoplasmic, though some studies indicate potential endoplasmic reticulum association. Its enzymatic activity appears pH-dependent, showing optimal function in neutral to slightly alkaline conditions.
Emerging evidence links RNPEPL1 to disease contexts. Transcriptomic analyses have identified altered expression in certain cancers, including hepatocellular carcinoma and gliomas, suggesting a possible role in tumor progression. Additionally, rare genetic variants in *RNPEPL1* have been tentatively associated with neurodevelopmental disorders, though mechanistic insights remain limited. Recombinant RNPEPL1 protein is frequently utilized in structural studies to elucidate catalytic mechanisms and inhibitor interactions, providing a foundation for therapeutic exploration. Further research is needed to clarify its endogenous substrates and regulatory networks in health and disease.
