Recombinant human NPEPL1 (Asparagine Peptidase-Like 1) protein is a product of the NPEPL1 gene, which encodes a putative metallopeptidase belonging to the M18 family. Although its precise biological role remains under investigation, NPEPL1 is hypothesized to function in cellular protein degradation or processing pathways, potentially through hydrolytic activity on specific peptide bonds. The protein shares structural homology with other M18 family members, such as aspartyl aminopeptidase (DNPEP), which are involved in cleaving N-terminal residues and regulating bioactive peptides. Recombinant NPEPL1 is typically expressed in heterologous systems like *E. coli* or mammalian cells, enabling studies on its enzymatic activity, substrate specificity, and interaction partners. Interest in NPEPL1 stems from its potential involvement in metabolic disorders, neurodegenerative diseases, or cancer, as suggested by differential expression patterns in diseased tissues. However, its exact physiological substrates and regulatory mechanisms require further elucidation. Recombinant forms of NPEPL1 are valuable tools for structural characterization (e.g., crystallography), biochemical assays, and screening for modulators that could inform therapeutic strategies. Current research focuses on clarifying its role in cellular homeostasis and disease contexts, leveraging recombinant protein to bridge gaps between genetic data and functional understanding.
