Recombinant human MAN1A2 (Mannosidase Alpha Class 1A Member 2) is a key enzyme involved in N-linked glycoprotein processing within the Golgi apparatus. As a member of the glycosyl hydrolase family 47. MAN1A2 functions as an α-1.2-mannosidase, trimming mannose residues from precursor oligosaccharides during glycoprotein maturation. This type II transmembrane protein localizes to the cis- and medial-Golgi compartments, where it participates in the quality control of protein folding by regulating glycan structure.
The protein’s enzymatic activity is crucial for proper glycoprotein trafficking and cellular communication. Dysregulation of MAN1A2 has been implicated in various pathological conditions, including cancer metastasis, neurodegenerative diseases, and immune disorders, due to its role in modulating cell adhesion and signaling pathways. Recombinant production of MAN1A2. typically achieved via mammalian expression systems (e.g., HEK293 or CHO cells), ensures proper post-translational modifications and enzymatic functionality. Purified recombinant MAN1A2 serves as a vital tool for studying glycosylation mechanisms, screening enzyme inhibitors, and investigating disease biomarkers. Its structural domains, including the catalytic TIM barrel motif and carbohydrate-binding site, make it a target for therapeutic interventions targeting protein glycosylation pathways.
