3-164 1.05e-101

GM2 activator protein (GM2-AP) is a non-enzymatic lysosomal protein that acts as cofactor in the sequential degradation of gangliosides. GM2A is an essential cofactor for beta-hexosaminidase A (Hex A) in the enzymatic hydrolysis of GM2 ganglioside to GM3. Mutation of the gene results in the AB variant of Tay-Sachs disease. GM2-AP and similar proteins belong to the ML domain family.

ML domain; ML domain - MD-2-related lipid recognition domain. This family consists of proteins from plants, animals and fungi, including dust mite allergen Der P 2. It has been implicate in lipid recognition, particularly in the recognition of pathogen related products. A mutation in Npc2 causes a rare form of Niemann-Pick type C2 disease. This domain has a similar topology to immunoglobulin domains.

Domain involved in innate immunity and lipid metabolism; ML (MD-2-related lipid-recognition) is a novel domain identified in MD-1, MD-2, GM2A, Npc2 and multiple proteins of unknown function in plants, animals and fungi. These single-domain proteins were predicted to form a beta-rich fold containing multiple strands, and to mediate diverse biological functions through interacting with specific lipids.
