Serine/threonine-protein kinase N1 is an enzyme that in humans is encoded by the PKN1 gene. [5] [6]
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]
Protein kinase N1 has been shown to interact with:
Cofilin 1 , also known as CFL1, is a human gene, part of the ADF/cofilin family.
Adapter molecule crk also known as proto-oncogene c-Crk is a protein that in humans is encoded by the CRK gene.
RAC(Rho family)-alpha serine/threonine-protein kinase is an enzyme that in humans is encoded by the AKT1 gene. This enzyme belongs to the AKT subfamily of serine/threonine kinases that contain SH2 protein domains. It is commonly referred to as PKB, or by both names as "Akt/PKB".
Mitogen-activated protein kinase 1, also known as ERK2, is an enzyme that in humans is encoded by the MAPK1 gene.
Serine/threonine-protein phosphatase PP1-alpha catalytic subunit is an enzyme that in humans is encoded by the PPP1CA gene.
LIM domain kinase 1 is an enzyme that in humans is encoded by the LIMK1 gene.
Calcium/calmodulin-dependent protein kinase type IV is an enzyme that in humans is encoded by the CAMK4 gene.
Serine/threonine-protein kinase 4 is an enzyme that in humans is encoded by the STK4 gene.
14-3-3 protein beta/alpha is a protein that in humans is encoded by the YWHAB gene.

Serine/threonine-protein kinase N2 is an enzyme that in humans and Strongylocentrotus purpuratus is encoded by the PKN2 gene.
Dual specificity protein kinase CLK1 is an enzyme that in humans is encoded by the CLK1 gene.
Mitogen-activated protein kinase 12 is an enzyme that in humans is encoded by the MAP3K12 gene.
Dual specificity testis-specific protein kinase 1 is an enzyme that in humans is encoded by the TESK1 gene.
PKN3 is a protein kinase C-related molecule and thought to be an effector mediating malignant cell growth downstream of activated phosphoinositide 3-kinase (PI3K). It is thought that chronic activation of the phosphoinositide 3-kinase (PI3K)/PTEN signal transduction pathway contributes to metastatic cell growth and that PKN3 may mediate that growth.1
