May play a role in the regulation of cell cycle progression, actin cytoskeleton assembly, cell migration, cell adhesion and transcription activation signaling processes.
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 transcription regulation. Regulates the cytoskeletal network by phosphorylating proteins such as VIM and neurofilament proteins NEFH, NEFL and NEFM, leading to inhibit their polymerization. Phosphorylates 'Ser-575', 'Ser-637' and 'Ser-669' of MAPT/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 'Thr-11' of histone H3 (H3T11ph), a specific tag for epigenetic transcriptional activation that promotes demethylation of histone H3 'Lys-9' (H3K9me) by KDM4C/JMJD2C. Phosphorylates HDAC5, HDAC7 and HDAC9, leading to impair their import in the nucleus. Phosphorylates 'Thr-38' of PPP1R14A, 'Ser-159', 'Ser-163' and 'Ser-170' of MARCKS, and GFAP. Able to phosphorylate RPS6 in vitro.

PKN, also called Protein-kinase C-related kinase (PRK), is a serine/threonine protein kinase that can be activated by the small GTPase Rho, and by fatty acids such as arachidonic and linoleic acids. It is involved in many biological processes including cytoskeletal regulation, cell adhesion, vesicle transport, glucose transport, regulation of meiotic maturation and embryonic cell cycles, signaling to the nucleus, and tumorigenesis. In some vertebrates, there are three PKN isoforms from different genes (designated PKN1, PKN2, and PKN3), which show different enzymatic properties, tissue distribution, and varied functions. PKN proteins contain three HR1 domains, a C2 domain, and a kinase domain. This model characterizes the second HR1 domain of PKN. HR1 domains are anti-parallel coiled-coil (ACC) domains that bind small GTPases from the Rho family. Length = 71

PKN3, also called PKNbeta, is a serine/threonine protein kinase that is activated by the Rho family of small GTPases, preferentially by RhoC. Both PKN1 and RhoC show limited and barely detectable expression in normal tissues, but are both upregulated in cancer cells, particularly in late-stage malignancies. PKN3 has been implicated to play a role in the metastatic growth and invasiveness of cancer cells, downstream of the oncogenic phosphoinositide 3-kinase signaling network. PKN3 shares a common domain architecture with other PKNs, containing three HR1 domains, a C2 domain, and a kinase domain. In addition, PKN3 contains two proline-rich regions between its C2 and kinase domains, and has been shown to associate with SH3 domain containing proteins like GRAFs, GAP for RhoA, and Cdc42Hs. This model characterizes the second HR1 domain of PKN3. HR1 domains are anti-parallel coiled-coil (ACC) domains that bind small GTPases from the Rho family; PKN3 binds Rho family GTPases, preferentially RhoC. Length = 74

PKN2, also called PKNgamma or Protein-kinase C-related kinase 2 (PRK2), is a serine/threonine protein kinase and an effector of the small GTPase Rho/Rac. It regulates G2/M cell cycle progression and the exit from cytokinesis. It also phosphorylates hepatitis C virus (HCV) RNA polymerase and thus, plays a role in HCV RNA replication. PKN2 shares a common domain architecture with other PKNs, containing three HR1 domains, a C2 domain, and a kinase domain. In addition, PKN2 contains a proline-rich region in between its C2 and kinase domains and has been shown to associate with SH3 domain containing proteins like NCK and Grb4. This model characterizes the second HR1 domain of PKN2. HR1 domains are anti-parallel coiled-coil (ACC) domains that bind small GTPases from the Rho family; PKN2 specifically binds to RhoA GTPase in a GTP-dependent manner. The HR1 domains of PKN2, together with its C2 domain, also facilitate the recruitment of PKN2 to primordial junctions at nascent cell-cell contacts, where it promotes junctional maturation. Length = 74

PKN1, also called PKNalpha or Protein-kinase C-related kinase 1 (PRK1), is a serine/threonine protein kinase that is activated by the Rho family of small GTPases, and by fatty acids such as arachidonic and linoleic acids. It is expressed ubiquitously and is the most abundant PKN isoform in neurons. PKN1 is implicated in a variety of functions including cytoskeletal reorganization, cardiac cell survival, cell adhesion, and glucose transport, among others. PKN1 contains three HR1 domains, a C2 domain, and a kinase domain. This model characterizes the second HR1 domain of PKN1. HR1 domains are anti-parallel coiled-coil (ACC) domains that bind small GTPases from the Rho family; PKN1 binds the GTPases RhoA, RhoB, and RhoC, and can also interact weakly with Rac. Length = 78

Found in vertebrate PRK1 and yeast PKC1 protein kinases C; those found in rhophilin bind RhoGTP; those in PRK1 bind RhoA and RhoB. Rho family members function as molecular switches, cycling between inactive and active forms, controlling a variety of cellular processes. HR1 repeats often occur in tandem repeat arrangments, seperated by a short linker region.

Alpha-helical domain found in vertebrate PRK1 and yeast PKC1 protein kinases C. The HR1 in rhophilin bind RhoGTP; those in PRK1 bind RhoA and RhoB. Also called RBD - Rho-binding domain
>PF02185 HR1: Hr1 repeat; InterPro: IPR000861 The HR1 repeat was first described as a three times repeated homology region of the N-terminal non-catalytic part of protein kinase PRK1(PKN) []
The first two of these repeats were later shown to bind the small G protein rho [, ] known to activate PKN in its GTP-bound form. Similar rho-binding domains also occur in a number of other protein kinases and in the rho-binding proteins rhophilin and rhotekin. Recently, the structure of the N-terminal HR1 repeat complexed with RhoA has been determined by X-ray crystallography []. It forms an antiparallel coiled-coil fold termed an ACC finger.
