DNM2

Dynamin-2 is a protein that in humans is encoded by the DNM2 gene.

Function
Dynamins represent one of the subfamilies of GTP-binding proteins. These proteins share considerable sequence similarity over the N-terminal portion of the molecule, which contains the GTPase domain. Dynamins are associated with microtubules. They have been implicated in cell processes such as endocytosis and cell motility, and in alterations of the membrane that accompany certain activities such as bone resorption by osteoclasts. Dynamins bind many proteins that bind actin and other cytoskeletal proteins. Dynamins can also self-assemble, a process that stimulates GTPase activity. Four alternatively spliced transcripts encoding different proteins have been described. Additional alternatively spliced transcripts may exist, but their full-length nature has not been determined.

Interactions
DNM2 has been shown to interact with:
 * SHANK1,
 * SHANK2, and
 * SNX9.

Clinical relevance
Mutations in this gene have been associated to cases of acute lymphoblastic leukaemia, or congenital myopathy (centronuclear type).
