Function

The large binding pocket can accommodate several single chain phospholipids and fatty acids, GM2A also exhibits some calcium-independent phospholipase activity (By similarity). Binds gangliosides and stimulates ganglioside GM2 degradation. It stimulates only the breakdown of ganglioside GM2 and glycolipid GA2 by beta-hexosaminidase A. It extracts single GM2 molecules from membranes and presents them in soluble form to beta-hexosaminidase A for cleavage of N-acetyl-D-galactosamine and conversion to GM3 (By similarity). Has cholesterol transfer activity (PubMed:17552909).

Notes

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

For more information, read more on recombinant antibodies.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.

Activity summary

The human GM2A also known as GM2 activator protein functions mechanically as a lysosomal lipid transfer protein. It possesses a mass of approximately 23 kDa. It is expressed mainly in the tissues that have a high lysosomal activity like the brain. It binds specific glycolipids such as GM2 ganglioside facilitating their interaction with enzymatic components in the lysosome.

Biological function summary

The GM2A protein belongs to a family of proteins that assist in the degradation of complex lipids. It is an essential component of the ganglioside degradation process where it acts as a cofactor rather than being part of any complex. GM2A helps transfer lipids to enzymes such as β-hexosaminidase A ensuring proper breakdown and recycling of gangliosides particularly in neuronal tissues.

Pathways

GM2A plays an important role in the lysosomal degradation pathway specifically involving lipid metabolism. The degradation of gangliosides utilizes GM2A to facilitate interaction between GM2 ganglioside and proteins such as β-hexosaminidase A a necessary step in breaking down these complex lipids. Another significant pathway relates to its role in maintaining the balance of sphingolipid metabolism highlighting its collaboration with enzymes involved in this process.

Associated diseases and disorders

Impaired activity or mutation in GM2A can lead to lipid storage diseases notably Tay-Sachs disease. Errors in GM2A disrupt the breakdown of gangliosides resulting in harmful accumulation within lysosomes. This dysfunction also involves the β-hexosaminidase A enzyme reinforcing the link between these proteins in the pathological buildup of gangliosides associated with Tay-Sachs disease.
