Recombinant human SUMF2 (sulfatase modifying factor 2) is a protein involved in the post-translational activation of sulfatases, enzymes critical for hydrolyzing sulfate esters in various metabolic pathways. Belonging to the SUMF family, SUMF2 shares structural homology with SUMF1. a key molecular chaperone required for the oxidation of a conserved cysteine residue in sulfatases to formylglycine, a catalytic moiety essential for their activity. However, unlike SUMF1. SUMF2 does not directly activate sulfatases. Instead, it may modulate SUMF1’s function by competing for binding to sulfatases or regulating their trafficking, acting as a potential negative regulator. Structurally, SUMF2 contains a conserved N-terminal signal peptide, secretory pathway retention motifs, and characteristic cysteine-rich domains critical for its interaction with sulfatases. It localizes predominantly in the endoplasmic reticulum. Although its exact physiological role remains under investigation, SUMF2 is thought to fine-tune sulfatase activity, impacting processes like glycosaminoglycan degradation, hormone metabolism, and lysosomal function. Dysregulation of sulfatases is linked to inherited disorders such as mucopolysaccharidoses and metachromatic leukodystrophy. Recombinant SUMF2 is produced via heterologous expression systems (e.g., E. coli or mammalian cells) for studying sulfatase regulation, developing therapies for sulfatase deficiencies, or exploring its role in cancer and metabolic diseases. Current research focuses on its molecular interactions, regulatory mechanisms, and therapeutic potential.
