Recombinant human XPMC2H protein is a genetically engineered variant of the XPMC2H (X-prolyl aminopeptidase-like protein 2 homolog) protein, produced using expression systems such as *E. coli*, yeast, or mammalian cells. While detailed structural and functional studies on XPMC2H remain limited, bioinformatics analyses suggest it may belong to the metalloprotease M24 family, characterized by conserved peptidase domains and potential metal-binding motifs. This protein is hypothesized to play roles in peptide processing, cellular metabolism, or stress-response pathways, though its exact physiological substrates and mechanisms require further validation. Its recombinant form enables researchers to investigate biochemical properties, enzyme kinetics, and interactions with other biomolecules in vitro. Interest in XPMC2H also stems from potential links to human diseases, including cancer or neurodegenerative disorders, where dysregulation of proteolytic activity is often implicated. Recombinant XPMC2H serves as a critical tool for antibody production, structural studies (e.g., X-ray crystallography), and high-throughput drug screening to identify modulators of its activity. However, functional ambiguity necessitates cautious interpretation of experimental data. Current research focuses on elucidating its cellular localization, post-translational modifications, and cross-species conservation to clarify its biological significance. This protein exemplifies the growing emphasis on characterizing understudied human proteins to expand the druggable proteome.
