MANBA (Mannosidase Beta): MANBA is a gene that encodes a lysosomal enzyme responsible for breaking down N-linked glycoproteins. It catalyzes the hydrolysis of beta-linked mannose residues, playing a crucial role in glycoprotein degradation. A deficiency in MANBA activity can cause lysosomal storage disorders, leading to the accumulation of undegraded glycoproteins and disrupting cellular function.
