A protein kinase that is specific to the amino acids serine and threonine is known as a mitogen-activated protein kinase (MAPK or MAP kinase; also known as a serine/threonine-specific protein kinase).
<h3>Mitogen-activated protein kinase :</h3>
A small number of cell surface receptors can ultimately generate a large intracellular response due to activation of kinase cascades.
In order to trigger an appropriate physiological response, such as cellular proliferation, differentiation, development, inflammatory reactions, and death in mammalian cells, MAPK pathways relay, amplify, and integrate information from a variety of stimuli.
Tyrosine phosphorylation, specifically numerous tyrosines on each RTK in the dimer, is how cross-linking triggers the tyrosine kinase activity in these RTKs. The term "cross-phosphorylation" refers to this action.
The activation of a MAPKKKK or MAPKKK by stimulation of plasma membrane receptors is the initial stage of signal transduction. The MAPKKK then phosphorylates two serine or threonine residues in the S/T-X5-S/T (X is any amino acid) motif of its activation loop, activating a downstream MAPKK.

Explanation:
does this come for a story or is just a question?
The correct answer is a theory.
A theory is a rational and contemplative kind of generalizing or abstract thinking or the outcomes of such thinking. On the basis of the context, the outcomes might involve generalized illustrations of how nature functions.
A theory can be a source of knowledge that may or may not is related to the specific explanatory models. To theorize is to create the body of knowledge.
A cell membrane protects a cell from it's surroundings. The cell membrane controls the movement of substances from the outside and inside of cells and organelles.
