The protein kinase C enzymes are known for their long-term activation: They remain activated after the original activation signal or the Ca 2+-wave is gone. It is presumed that this is achieved by the production of diacylglycerol from phosphatidylinositol by a phospholipase ; fatty acids may also play a role in long-term activation.
Protein kinase C (PKC) is a family of serine- and threonine-specific protein kinases that can be activated by calcium and the second messenger diacylglycerol. PKC family members phosphorylate a wide variety of protein targets and are known to be involved in diverse cellular signaling pathways.
Protein kinase C and Rho-associated protein kinase are involved in regulating calcium ion intake; these calcium ions, in turn stimulate a myosin light chain kinase, forcing a contraction. [5] Rho-associated protein kinase are serine or threonine kinases that determine the calcium sensitivity in smooth muscle cells.

Above is a ball-and-stick model of the inorganic phosphate molecule (H PO 4 2−).Colour coding: P (orange); O (red); H (white). The chemical activity of a protein kinase involves removing a phosphate group from ATP and covalently attaching it to one of three amino acids that have a free hydroxyl group.
Protein kinase C theta (PKC-θ) is an enzyme that in humans is encoded by the PRKCQ gene. [5] PKC-θ, a member of serine/threonine kinases, is mainly expressed in hematopoietic cells [5] with high levels in platelets and T lymphocytes, where plays a role in signal transduction. Different subpopulations of T cells vary in their requirements of ...
[4] [44] [45] [46] One example of a protein that binds to adaptor proteins and become activated is PLC that is very important in the lymphocyte signal pathways. PLC is responsible for PKC activation, via DAG and Ca 2+, which leads to phosphorylation of CARMA1 molecule, and formation of CBM complex.
PDPK1 is a master kinase, which is crucial for the activation of AKT/PKB and many other AGC kinases including PKC, S6K, SGK. An important role for PDPK1 is in the signaling pathways activated by several growth factors and hormones including insulin signaling.
