Recombinant human USP49 (Ubiquitin-Specific Protease 49) is a genetically engineered protein belonging to the ubiquitin-specific protease family, a subclass of deubiquitinating enzymes (DUBs). These enzymes regulate protein stability and function by cleaving ubiquitin moieties from substrate proteins, thereby counteracting ubiquitination-mediated degradation or signaling. USP49 is a cysteine protease characterized by a conserved catalytic domain with a Cys-His-Asp/Asn triad, essential for its enzymatic activity, and unique C-terminal regions that may mediate substrate specificity or subcellular localization.
Functionally, USP49 has been implicated in diverse cellular processes, including transcriptional regulation, RNA processing, and epigenetic modulation. Studies suggest its role in stabilizing chromatin-associated proteins by removing ubiquitin marks, influencing gene expression, and maintaining genomic integrity. For instance, USP49 interacts with histones or transcription factors to modulate histone modifications or RNA polymerase II activity. Emerging evidence also links USP49 to innate immune responses, particularly in antiviral pathways, by targeting viral or host proteins for deubiquitination.
In physiological and pathological contexts, USP49 dysregulation is associated with cancer progression, neurodevelopmental disorders, and viral infections. However, its mechanistic details remain understudied compared to other DUBs. Recombinant USP49 protein, typically expressed in mammalian or bacterial systems, is critical for in vitro studies to dissect its enzymatic kinetics, substrate profiles, and structural properties, aiding therapeutic exploration targeting DUB-related diseases. Ongoing research focuses on elucidating its regulatory networks and disease-specific roles for potential diagnostic or therapeutic applications.
