Disease relevance of Dctn1

 

High impact information on Dctn1

  • Dynein and dynactin complex components concentrate on the nuclear envelope prior to any changes in nuclear envelope organization [2].
  • Cytoplasmic dynein is the major minus end-directed microtubule motor in animal cells, and associates with many of its cargoes in conjunction with the dynactin complex [3].
  • Motility of apoptotic membranes is restored by recruitment of intact cytoplasmic dynein and dynactin from control cytosol, or from apoptotic cytosol supplemented with purified cytoplasmic dynein--dynactin, demonstrating the dynamic nature of the association of cytoplasmic dynein and dynactin with their membrane cargo [3].
  • On the basis of these results, we conclude that cytoplasmic dynein and dynactin are essential for the transport of microtubules from the centrosome into the axon [4].
  • Evidence is provided for a dynactin-associated kinase required for dynein-mediated vesicle transport [5].
 

Biological context of Dctn1

 

Anatomical context of Dctn1

 

Associations of Dctn1 with chemical compounds

  • In order to clone the p24 subunit, the components of purified dynactin were resolved by SDS polyacrylamide gel electrophoresis [12].
  • This polypeptide co-sediments with dynactin on sucrose density gradients and it also co-immunoprecipitates with dynactin, but not with kinesin or cytoplasmic dynein [12].
 

Physical interactions of Dctn1

 

Other interactions of Dctn1

  • As compared with early vesicles, late vesicles had reduced association with receptor, Rab4, and kinesin I but were highly associated with dynein, Rab7, dynactin, and KIF3A [14].
  • Secretory granules of non-polarized chromaffin cells of the bovine adrenal medulla, that are assumed to underlie microtubular plus end targeting from the Golgi apparatus to the cell periphery, were not found to be associated with dynein or dynactin [15].
  • We investigated whether the motor protein cytoplasmic dynein and dynactin, a protein complex thought to link dynein with vesicles, are present in rat renal collecting ducts and associated with aquaporin-2 (AQP2)-bearing vesicles [16].
