This gene encodes a member of the dynamin subfamily of GTP-binding proteins. The encoded protein possesses unique mechanochemical properties used to tubulate and sever membranes, and is involved in clathrin-mediated endocytosis and other vesicular trafficking processes. Actin and other cytoskeletal proteins act as binding partners for the encoded protein, which can also self-assemble leading to stimulation of GTPase activity. More than sixty highly conserved copies of the 3' region of this gene are found elsewhere in the genome, particularly on chromosomes Y and 15. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]
Forensic Context
A study in mice demonstrated that the DNM1 gene, which encodes dynamin 1, was identified as part of a common cosplicing network of glutamatergic synapse genes in brain reward circuitry regions of animals selectively bred for differential risk for voluntary methamphetamine intake [Hitzemann et al. DOI:10.3390/brainsci9070155].
