PKN2 (Q16513) - Overview - Molecular Target Synopsis
PKN2, Serine/threonine-protein kinase N2
Enzyme Classification 18.104.22.168
Also Known as PKN2_HUMAN, PKN2, PRK2, PRKCL2
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 (PubMed:27104747)., (Microbial infection) Phosphorylates HCV NS5B leading to stimulation of HCV RNA replication. Interacts (via the REM repeats) with RHOA (GTP-bound form preferentially) and interacts (via the REM repeats) with RAC1 (GTP-bound form preferentially); the interactions induce its autophosphorylation (PubMed:9121475, PubMed:20974804). Interacts with RHOC (PubMed:20974804). Interacts with NCK1 and NCK2 (PubMed:10026169). Interacts with NCK1 (via SH3 domains) (By similarity). Interacts with CD44 (PubMed:15123640). Interacts (via C-terminal kinase domain) with PDPK1; the interaction stimulates PDPK1 kinase activity (PubMed:10226025, PubMed:10792047, PubMed:11781095, PubMed:18835241). Interacts with MAP3K2; the interaction activates PRK2 kinase activity in a MAP3K2-independent kinase activity (PubMed:10818102). Interacts (via C-terminal domain) with AKT1; the interaction occurs with the C-terminal cleavage product of PRK2 in apoptotic cells (PubMed:10926925). Interacts (via C-terminus) with PTPN13 (via PDZ 3 domain) (PubMed:11356191). Interacts with CDK10 (PubMed:27104747).
