抗人 SUMF1 抗体对
01AB01368
Sulfatase modifying factor 1 (SUMF1) is a glycosylated enzyme localized primarily in the endoplasmic reticulum (ER) and is essential for the post-translational activation of all eukaryotic sulfatases by converting a specific cysteine residue in their active site to C-alpha-formylglycine (FGly), a modification necessary for their catalytic activity. SUMF1 can also be secreted and subsequently taken up by cells, where it is trafficked back to the ER and remains functionally active, enhancing sulfatase activities in various tissues. Both glycosylated and non-glycosylated forms of SUMF1 can be secreted, but only the glycosylated form is efficiently internalized by cells through a receptor-mediated process. Mutations in the SUMF1 gene can disrupt FGly formation, leading to inactive sulfatases and causing multiple sulfatase deficiency (MSD), a rare lysosomal storage disorder characterized by the combined loss of function of all sulfatases, resulting in the accumulation of sulfated substrates and severe clinical symptoms.
