Gm2a - ganglioside GM2 activator

Enables lipid transporter activity and phospholipase activator activity. Contributes to beta-N-acetylgalactosaminidase activity. Involved in ganglioside metabolic process; lipid transport; and positive regulation of hydrolase activity. Located in several cellular components, including apical plasma membrane; basolateral plasma membrane; and cytoplasmic side of plasma membrane. Human ortholog(s) of this gene implicated in GM2 gangliosidosis and GM2 gangliosidosis, AB variant. Orthologous to human GM2A (GM2 ganglioside activator).
