MANBA (Mannosidase Beta): MANBA is a gene that encodes a lysosomal enzyme involved in the breakdown of N-linked glycoproteins. It catalyzes the hydrolysis of beta-linked mannose residues, playing a key role in glycoprotein degradation. Deficiencies in MANBA activity can lead to lysosomal storage disorders, resulting in the accumulation of undegraded glycoproteins and impairing cellular function.
