- Name: pkn
- Organism: JCVI-Syn3.0
- UniProt ID: F4MPD0
- Description: Unknown function. According to a protein blast, this gene is most likely a "serine/threonine protein kinase". A serine/threonine protein kinase is a kinase enzyme that phosphorylates the OH group of serine or threonine (which have similar sidechains). Serine/threonine protein kinase describes a class of enzymes that belong to the family of transferases, specifically protein-serine/threonine kinases. These enzymes transfer phosphates to the oxygen atom of a serine or threonine sidechain in proteins. This process is called phosphorylation. Protein phosphorylation in particular plays a significant role in a wide range of cellular processes and is a very important posttranslational modification. The chemical reaction performed by these enzymes can be written as ATP + a protein -> ADP + a phosphoprotein. Thus, the two substrates of this enzyme are ATP and a protein, whereas its two products are ADP and phosphoprotein. The protein encoded by this gene (pkn) belongs to the protein kinase C superfamily. 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. 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.

- Equivalent E. coli functional protein: EG11831.
- Expression Level: [Low].
- Expression Level Hypothesis: This enzyme phosphorylates the OH group of serine or threonine. Protein phosphorylation plays a significant role in a wide range of cellular processes and is a very important posttranslational modification, meaning it is probably relatively important to be abundant in the cell. The dataset shows that the expression level for for prkC (serine/threonine protein kinase, putative) is low, meaning that serine/threonine protein kinase might not be an amino acid commonly used in this organism's proteins.

- Expression Time: [Early].
- Expression Level Hypothesis: Because protein phosphorylation plays a significant role in a wide range of cellular processes and is a very important posttranslational modification, it can be expressed at different times within an organism's lifecycle. Since it is involved in various processes such as regulation of the intermediate filaments of the actin cytoskeleton, cell migration, tumor cell invasion and transcription regulation, it is probably expressed early on.
- Expression Time References and Description: Serine/threonine-specific protein kinase
- Other Components in the functional module: Phosphatidylcholine (PC)-specific phospholipases D (PLDs) catalyze the hydrolysis of PC to produce phosphatidic acid and choline, needed. PLD1 encodes a phosphatidylcholine-specific phospholipase, necessary for protein phosphorylation.
