Sign in to saveAlso known as Dynamin-type guanine nucleotide-binding (G) domain, protein family, IPR030381, dynamins
Dynamin is a GTPase protein responsible for endocytosis in the eukaryotic cell. Dynamin is part of the "dynamin superfamily", which includes classical dynamins, dynamin-like proteins, Mx proteins, OPA1, mitofusins, and GBPs. Members of the dynamin family are principally involved in the scission of newly formed vesicles from the membrane of one cellular compartment and their targeting to, and fusion with, another compartment, both at the cell surface (particularly caveolae internalization) as well as at the Golgi apparatus. Dynamin family members also play a role in many processes including div

Dinaminas são guanosina trifosfatases de 96 kDa (GTPase) essenciais para inúmeros eventos de tráfico de membrana intracelular. Na membrana plasmática, a atividade GTPase de dinamina é necessária para a reciclagem de vesículas sinápticas, endocitose mediada por receptores e internalização de caveola. A molécula mostrou-se envolvida na endocitose mediada pelo receptor de transferrina e EGF, GLUT-4, receptores de opióides e receptores acoplados a proteínas G. Além disso, recentemente, a atuação da dinamina foi descoberta também no tráfico dentro e fora do aparato de Golgi. [CELL] Existem no entanto vesículas como as e COPII que aparentemente são capazes de se separar sem a necessidade de uma GTPase como a dinamina. A diferença entre os dois processos ainda é desconhecida [MCB].
