Abstract

The contribution of discrete voltage-gated potassium channels (KChs) to nerve function reflects their densities over the cell surface. Even so, the mechanisms that regulate the surface densities of these, and other membrane proteins, are largely unknown. Based on the recent identification of ubiquitin conjugation as a pivotal cue for protein internalisation, and the co- incidence between internalisation and putative ubiquitination (UbE) motifs in Kvl.4 KChs, it is hypothesized that ubiquitination controls the cell surface residency of KChs. This project will test his notion by defining the ability, necessity and sufficiency of UbE motifs to direct the internalisation and ubiquitination of select KChs and reporter proteins in transfected cells. In parallel, interacting proteins, and thus control mechanisms, will be identified using the yeast two-hybrid system.
