Accumulates during telophase at the cleavage furrow and concentrates finally around the midbody in cytokinesis. Recruited to nascent cell-cell contacts at the apical surface of cells. In the course of viral infection, colocalizes with HCV NS5B at perinuclear region in the cytoplasm.

Western Blot (WB)

(Western blot analysis of PRK1/2 (Phospho-Thr774/816) using Na2VO3 treated HepG2 whole cell lysates.-/+ means absence or presence of N peptide（non-phospho peptide) and P peptide(phospho peptide).)

Immunohistochemistry (IHC)

(Staining Rat heart tissue by IHC-P. The sample was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The sample was then blocked and incubated with the primary antibody at 4 degree C overnight. An HRP conjugated anti-Rabbit antibody was used as the secondary antibody.)

PKC-related serine/threonine-protein kinase and Rho/Rac effector protein that participates in specific signal transduction responses in the cell. Plays a role in the regulation of cell cycle progression, actin cytoskeleton assembly, cell migration, cell adhesion, tumor cell invasion and transcription activation signaling processes. Phosphorylates CTTN in hyaluronan-induced astrocytes and hence decreases CTTN ability to associate with filamentous actin. Phosphorylates HDAC5, therefore lead to impair HDAC5 import. Direct RhoA target required for the regulation of the maturation of primordial junctions into apical junction formation in bronchial epithelial cells. Required for G2/M phases of the cell cycle progression and abscission during cytokinesis in a ECT2-dependent manner. Stimulates FYN kinase activity that is required for establishment of skin cell-cell adhesion during keratinocytes differentiation. Regulates epithelial bladder cells speed and direction of movement during cell migration and tumor cell invasion. Inhibits Akt pro-survival-induced kinase activity. Mediates Rho protein-induced transcriptional activation via the c-fos serum response factor (SRF). Involved in the negative regulation of ciliogenesis. (Microbial infection) Phosphorylates HCV NS5B leading to stimulation of HCV RNA replication.

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.
