Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events. Proteins responsible for detecting stimuli are generally termed receptors , although in some cases the term sensor is used. [ 1 ]
The entire set of cell changes induced by receptor activation is called a signal transduction mechanism or pathway. [44] Key components of a signal transduction pathway (MAPK/ERK pathway shown) A more complex signal transduction pathway is the MAPK/ERK pathway, which involves changes of protein–protein interactions inside the cell, induced by ...
In cell biology, there are a multitude of signalling pathways. Cell signalling is part of the molecular biology system that controls and coordinates the actions of cells.. Akt/PKB signalling pathway
Figure of the three main pathways of Wnt signaling in biological signal transduction. The Wnt protein family includes a large number of cysteine -rich glycoproteins . The Wnt proteins activate signal transduction cascades via three different pathways, the canonical Wnt pathway , the noncanonical planar cell polarity (PCP) pathway , and the ...
The ions are normally bound or stored in intracellular components (such as the endoplasmic reticulum(ER)) and can be released during signal transduction. The enzyme phospholipase C produces diacylglycerol and inositol trisphosphate , which increases calcium ion permeability into the membrane.
There are three kinds of contextual factors that determine the shape the TGF-β response: the signal transduction components, the transcriptional cofactors and the epigenetic state of the cell. The different ligands and receptors of TGF-β are significant as well in the composition signal transduction pathway. [2]
Ethylene chemical structure. Ethylene signaling pathway is a signal transduction in plant cells to regulate important growth and developmental processes. [1] [2] Acting as a plant hormone, the gas ethylene is responsible for promoting the germination of seeds, ripening of fruits, the opening of flowers, the abscission (or shedding) of leaves and stress responses. [3]
The JAK-STAT signaling pathway is a chain of interactions between proteins in a cell, and is involved in processes such as immunity, cell division, cell death, and tumor formation. The pathway communicates information from chemical signals outside of a cell to the cell nucleus , resulting in the activation of genes through the process of ...
