Description:
Rab guanosine triphosphatases regulate vesicular transport and membrane traffic within eukaryotic cells. Here, a kinesin-like protein that interacts with guanosine triphosphate (GTP)-bound forms of Rab6 was identified. This protein, termed Rabkinesin-6, was localized to the Golgi apparatus and shown to play a role in the dynamics of this organelle. The carboxyl-terminal domain of Rabkinesin-6, which contains the Rab6-interacting domain, inhibited the effects of Rab6-GTP on intracellular transport. Thus, a molecular motor is a potential effector of a Rab protein, and coordinated action between members of these two families of proteins could control membrane dynamics and directional vesicular traffic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Echard, A -- Jollivet, F -- Martinez, O -- Lacapere, J J -- Rousselet, A -- Janoueix-Lerosey, I -- Goud, B -- New York, N.Y. -- Science. 1998 Jan 23;279(5350):580-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Unite Mixte de Recherche CNRS 144 et 168, Institut Curie, 26 rue d'Ulm, 75248 Paris Cedex 05, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9438855" target="_blank"〉PubMed〈/a〉
