Dynamin-1 is a protein that in humans is encoded by the DNM1 gene.[1][2]

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.[3]

Interactions

DNM1 has been shown to interact with Amphiphysin,[4][5][6][7][8] FNBP1,[9] NCK1,[10] PACSIN1,[9][11] Grb2[12][13] and SH3GL2.[4][14]
