Abstract:ERM proteins are conserved regulators of cortical membrane specialization, that function as membrane-actin linkers and molecular hubs. Activity of ERM proteins requires a conformational switch from an inactive cytoplasmic form into an active membrane-and actinbound form, which is thought to be mediated by sequential PIP2-binding and phosphorylation of a conserved C-terminal threonine residue. Here, we use the single C. elegans ERM ortholog, ERM-1, to study the contribution of these regulatory events to ERM act… Show more
