| Type: | Domain | Name: | GRAM domain |
| Description: | The GRAM domain is found in glucosyltransferases, myotubularins and other putative membrane-associated proteins. It is normally about 70 amino acids in length. It is thought to be an intracellular protein-binding or lipid-binding signalling domain, which has an important function in membrane-associated processes. The structure of the GRAM domain is similar to that found in PH domains []. Mutations in the GRAM domain of myotubularins cause a muscle disease, which suggests that the domain is essential for the full function of the enzyme []. Myotubularin-related proteins are a large subfamily of protein tyrosine phosphatases (PTPs) that dephosphorylate D3-phosphorylated inositol lipids []. | Short Name: | GRAM |
