Dock6 was identified as one of a family of proteins which share high sequence similarity with Dock180, the archetypal member of the DOCK family.[2] It has a similar domain arrangement to other DOCK proteins,[3] with a DHR1 domain known in other proteins to bind phospholipids,[4] and a DHR2 domain containing the GEF activity.[5]
Function
There is currently very little information about the cellular role of this protein. However, Dock6 has been reported to exhibit dual GEF specificity towards the small G proteins Rac1 and Cdc42.[6] It is the only DOCK family member reported to activate both of these G proteins. The same study also showed that transfection of the Dock6 DHR2 domain into N1E-115 neuroblastoma cells promoted Rac- and Cdc42-dependent neurite outgrowth, although the physiological significance of this has yet to be demonstrated.
