NCBI Description
The protein encoded by this gene belongs to the protein kinase C superfamily. This kinase is activated by Rho family of small G proteins and may mediate the Rho-dependent signaling pathway. This kinase can be activated by phospholipids and by limited proteolysis. The 3-phosphoinositide dependent protein kinase-1 (PDPK1/PDK1) is reported to phosphorylate this kinase, which may mediate insulin signals to the actin cytoskeleton. The proteolytic activation of this kinase by caspase-3 or related proteases during apoptosis suggests its role in signal transduction related to apoptosis. Alternatively spliced transcript variants encoding distinct isoforms have been observed. [provided by RefSeq, Jul 2008]
Uniprot Description
PKN1: an AGC kinase of the PKN family. A PKC-related serine/threonine-protein kinase involved in various processes such as regulation of the intermediate filaments of the actin cytoskeleton, cell migration, tumor cell invasion and transcriptional regulation. Regulates the cytoskeletal network by phosphorylating intermediate filament proteins such as VIM and NFH, NFL and NFM, inhibiting their polymerization. Phosphorylates Tau, lowering its ability to bind to microtubules, resulting in disruption of tubulin assembly. Acts as a key coactivator of androgen receptor (ANDR)-dependent transcription, by being recruited to ANDR target genes and specifically mediating phosphorylation of H3T11, a specific tag for epigenetic transcriptional activation that promotes demethylation of histone H3K9me by JMJD2C. Phosphorylates HDAC5, HDAC7 and HDAC9, impairing their import in the nucleus. Activated by lipids, particularly cardiolipin and to a lesser extent by other acidic phospholipids. Activated by CASP3 cleavage during apoptosis. Localization to endosomes is mediated via its interaction with RHOB. Accumulates during telophase at the cleavage furrow and finally concentrates around the midbody in cytokinesis. Three isoforms of the human protein are produced by alternative splicing.
