Description

Dynamin-2 is a ubiquitously expressed, membrane associated protein belonging to the Dynamin protein family of GTPases, a group consisting of three isoforms with distinct tissue specificity and function. Dynamin localizes to plasma membrane-coated pits by its interactions with amphiphysin through the dynamin PRD domain. Dynamin-2 is a component in the manufacture of microtubule bundles, and is capable of both binding and hydrolyzing GTP. It is also likely to be involved in the trafficking mechanisms for vesicles, especially those pertaining to endocytosis. Defects in the expression of Dynamin-2 have been shown to cause Charcot-Marie-Tooth disease dominant intermediate type B (CMTDIB), and centronuclear myopathy autosomal dominant (ADCNM). There is also some interest in Dynamin-2 as a potential regulator for adenovirus targeting cancer therapies.
