DNM3 encodes a member of a family of guanosine triphosphate (GTP)-binding proteins that associate with microtubules and are involved in vesicular transport. The encoded protein functions in the development of megakaryocytes. Alternative splicing results in multiple transcript variants. DNM3 (Dynamin 3) is a Protein Coding gene. Diseases associated with DNM3 include Optic Atrophy 1. Among its related pathways are RET signaling and MHC class II antigen presentation.
