Serine/threonine-protein kinase N1 is an enzyme that in humans is encoded by the PKN1 gene.[1][2]

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.[2]


Protein kinase N1 has been shown to interact with Phospholipase D1,[3] Phosphoinositide-dependent kinase-1,[4] Vimentin,[5] AKAP9,[6] CCDC85B,[7] Actinin, alpha 1,[8] NEFL,[9] NEUROD2[10] and RHOA.[11][12][13]
