| Formulation |
GM2AP1 was filtered (0.4um) and lyophilized from 0.5mg/ml in 0.05M Tris buffer and 0.1M NaCl, pH 8.0. |
| Solubility |
It is recommended to add deionized water to prepare a working stock solution of approximately 0.5mg/ml and let the lyophilized pellet dissolve completely. GM2AP1 is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture. |
| Purity |
Greater than 95.0% as determined by SDS-PAGE. |
| Description |
GM2AP1 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain (Ser33-Ile193) containing 170 amino acids including a 9 aa His tag at N-terminus. The total calculated molecular mass is 18.7kDa. |
| Protein Background |
GM2 Ganglioside Activator Pseudogene 1 (GM2AP1) is a small glycolipid transport protein which functions as a substrate specific co-factor for the lysosomal enzyme beta-hexosaminidase A. Beta-hexosaminidase A, along with GM2AP1, catalyzes the degradation of the ganglioside GM2, and other molecules containing terminal N-acetyl hexosamines. GM2AP1 protein is localized in lysosomes. GM2AP1 participates in lipid metabolism. GM2AP1 protein forms a large binding pocket for a number of single chain phospholipids and fatty acids. GM2AP1 displays calcium-independent phospholipase activity. GM2AP1 stimulates ganglioside GM2 degradation by presenting GM2 to beta-hexosaminidase A. GM2AP1 gene mutations result in GM2-gangliosidosis type AB or the AB variant of Tay-Sachs disease. |
