What is PKC in cell biology?

What is PKC in cell biology?

Protein Kinase C (PKC) is a family of serine–threonine kinases found in most cell types whose activity has a strong influence on a wide variety of signal transduction events.

What is protein kinase and why are they important?

Protein kinases are intracellular enzymes that regulate cell growth and proliferation as well as the triggering and regulation of immune responses. Protein kinases are important therapeutic targets in cancer because of their critical role in signalling mechanisms that drive malignant cell characteristics.

Where is PKC?

Abstract. Protein kinase C (PKC) consists of a family of closely related enzymes highly concentrated in the CNS. These enzymes respond to the second messengers calcium (Ca2+) and diacylglycerol (DAG), to express their activities at membrane locations.

How is PKC activated?

PKC enzymes in turn are activated by signals such as increases in the concentration of diacylglycerol (DAG) or calcium ions (Ca2+). Hence PKC enzymes play important roles in several signal transduction cascades.

What are kinases used for?

Kinases are used extensively to transmit signals and regulate complex processes in cells. Phosphorylation of molecules can enhance or inhibit their activity and modulate their ability to interact with other molecules.

What are the types of protein kinases?

There are two main types of protein kinase. The great majority are serine/threonine kinases, which phosphorylate the hydroxyl groups of serines and threonines in their targets and most of the others are tyrosine kinases, although additional types exist. Protein kinases are also found in bacteria and plants.

What does PKA stand for?

Difference Between pKa and pKb

pKa vs pKb
The negative logarithm of Ka is pKa. The negative logarithm of Kb is pKb.
The acid dissociation constant is related to pKa. The base dissociation constant is related to pKb.
Indications
The stronger the acid, the lower the pKa value. The weaker the base, the lower the pKb value.
