Summary: Enables diacylglycerol-dependent, calcium-independent serine/threonine kinase activity. Involved in cellular response to insulin stimulus; positive regulation of D-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 brush border. 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, Jan 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
