New
Stein et al., Albany, United States. In Cell Microbiol, Nov 2015

New
Villanueva et al., Santiago, Chile. In Biochem Biophys Res Commun, Nov 2015
The RNA-dependent RNA polymerase (RdRP) of the Hepatitis C virus (HCV), named NS5B, is phosphorylated by the cellular protein kinase C-related kinase 2 (PRK2) at two serine residues (Ser29 and Ser42) of the finger subdomain (genotype 1b).

New
Kinsella et al., Dublin, Ireland. In Oncotarget, Oct 2015
PRK1 is a member of a subfamily of three structurally related kinases comprising PRK1/PKNα, PRK2/PKNγ and PRK3/PKNβ that are widely yet differentially implicated in various cancers.
Rho Kinase Pathway Alterations in the Brain and Leukocytes in Huntington's Disease.
New
Hersch et al., United States. In Mol Neurobiol, Jun 2015
We investigated the messenger RNA (mRNA) expression of Rho kinase pathway genes, including RhoA (Ras homolog family member A), ROCK1 (Rho-associated kinase1), PRK2 (protein kinase C-related protein kinase 2), Profilin1, cofilin1, MYPT1 (myosin phosphatase target subunit 1), and LIMK1 (LIM domain kinase 1) in HD human blood leukocytes, postmortem brain, and in R6/2 HD mouse brain tissue using qPCR.
p38α deficiency and oxidative stress cause cytokinesis failure in hepatocytes.
Sastre et al., Valencia, Spain. In Free Radic Biol Med, 2014
Key proteins of the RhoA pathway (phospho-PRK2, nuclear phosphorylated cofilin, and cytosolic p27) were assessed confirming the impairment of this pathway.
Phosphorylation of hepatitis C virus RNA polymerases ser29 and ser42 by protein kinase C-related kinase 2 regulates viral RNA replication.
Oh et al., Seoul, South Korea. In J Virol, 2014
We previously showed that HCV RdRp is phosphorylated by protein kinase C-related kinase 2 (PRK2).
Constitutively active NDR1-PIF kinase functions independent of MST1 and hMOB1 signalling.
Hergovich et al., London, United Kingdom. In Cell Signal, 2014
Significantly, the analyses of these variants revealed that NDR1-PIF, an NDR1 variant containing the PRK2 hydrophobic motif, remains hyperactive independent of hMOB1/NDR1-PIF complex formation.
Protein Kinase C-Related Kinase (PKN/PRK). Potential Key-Role for PKN1 in Protection of Hypoxic Neurons.
Baier-Bitterlich et al., Innsbruck, Austria. In Curr Neuropharmacol, 2014
Serine/threonine protein kinase C-related kinase (PKN/PRK) is a family of three isoenzymes (PKN1, PKN2, PKN3), which are widely distributed in eukaryotic organisms and share the same overall domain structure.
Enzyme Kinetics and Distinct Modulation of the Protein Kinase N Family of Kinases by Lipid Activators and Small Molecule Inhibitors.
Timofeevski et al., In Biosci Rep, 2014
The known lipid effector, arachidonic acid, increased the catalytic efficiency of each isoform, mainly through an increase in kcat for PKN1 and PKN2, and a decrease in peptide KM for PKN3.
Manipulation of pro-inflammatory cytokine production by the bacterial cell-penetrating effector protein YopM is independent of its interaction with host cell kinases RSK1 and PRK2.
Rüter et al., Münster, Germany. In Virulence, 2013
The C-terminus of rYopM was identified to be essential for the interaction with RSK1, whereas any deletion in rYopM's leucin-rich repeat domains abrogated PRK2 binding.
Regulation of protein kinase C-related protein kinase 2 (PRK2) by an intermolecular PRK2-PRK2 interaction mediated by Its N-terminal domain.
GeneRIF

Destabilization of PDK1 by Hsp90 inactivation suppresses hepatitis C virus replication through inhibition of PRK2-mediated viral RNA polymerase phosphorylation.
GeneRIF
Oh et al., Seoul, South Korea. In Biochem Biophys Res Commun, 2012

The Rho target PRK2 regulates apical junction formation in human bronchial epithelial cells.
GeneRIF
Hall et al., New York City, United States. In Mol Cell Biol, 2011
Rho binding is essential for PRK2 function and facilitates PRK2 recruitment to junctions. Kinase-dead PRK2 acts as a dominant-negative mutant and prevents apical junction formation.
Regulatory domain selectivity in the cell-type specific PKN-dependence of cell migration.
GeneRIF
Parker et al., London, United Kingdom. In Plos One, 2010
PKN isoforms are not simply redundant in supporting migration, but appear to be linked through isoform specific regulatory domain properties to selective upstream signals. It

GeneRIF
Bliska et al., Stony Brook, United States. In Infect Immun, 2010
Yersinia pseudotuberculosis mutants expressing YopM proteins unable to interact with either RSK1 or PRK2 were defective for virulence in this assay, indicating that both interaction domains are important for YopM to promote pathogenesis.
