Enables protein kinase C activity. Involved in several processes, including cellular response to insulin stimulus; positive regulation of glucose import; and positive regulation of protein localization to plasma membrane. Acts upstream of or within actin filament organization; establishment of apical/basal cell polarity; and eye photoreceptor cell development. Located in several cellular components, including Schmidt-Lanterman incisure; apical plasma membrane; and nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; lung; and sensory organ. Used to study abdominal obesity-metabolic syndrome; obesity; and type 2 diabetes mellitus. Orthologous to human PRKCI (protein kinase C iota). [provided by Alliance of Genome Resources, Apr 2022]
