Protein

Serine/threonine-protein kinase N1

Gene

PKN1

Organism
Bos taurus (Bovine)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

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', and GFAP. Able to phosphorylate RPS6 in vitro (By similarity).By similarity

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Enzyme regulationi

Kinase activity is activated upon binding to Rho proteins (RHOA, RHOB and RAC1). Activated by lipids, particularly cardiolipin and to a lesser extent by other acidic phospholipids. Activated by caspase-3 (CASP3) cleavage during apoptosis. Two specific sites, Thr-776 (activation loop of the kinase domain) and Ser-918 (turn motif), need to be phosphorylated for its full activation (By similarity).By similarity
