Serine/threonine-protein kinase N1 is an enzyme that in humans is encoded by the PKN1 gene.^[5]^[6]

Function

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.^[6]

Interactions

Protein kinase N1 has been shown to interact with:

AKAP9,^[7]
Actinin, alpha 1,^[8]
CCDC85B,^[9]
NEFL,^[10]
NEUROD2^[11]
Phosphoinositide-dependent kinase-1,^[12]
Phospholipase D1,^[13]
RHOA,^[14]^[15]^[16] and
Vimentin.^[17]
TRAF1.^[18]
