It is abundant in several endocrine tissues and is concentrated at sites of plasma membrane activity, such as filopodia and microspikes, and induces cell expansion and process formation. It is post-translationally modified by prenylation and palmitoylation and the lipid anchor is necessary for function. See palmdelphin.
