Dynamin-1 is a protein that in humans is encoded by the DNM1 gene.^[5]^[6]

Function

Dynamin 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 dynamin, 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.^[7]

Role in disease

De novo mutations in DNM1 have been associated with a severe form of childhood epilepsy called developmental and epileptic encephalopathy. Most pathogenic variants are missense variants, and have been shown to impair synaptic vesicle endocytosis in a dominant negative manner.^[8]

Interactions

DNM1 has been shown to interact with:

AMPH,^[9]^[10]^[11]^[12]^[13]
FNBP1,^[14]
Grb2^[15]^[16]
NCK1,^[17]
PACSIN1,^[14]^[18] and
SH3GL2.^[9]^[19]
