Publisher Summary Signal transduction is the process where an external chemical signal elicits an intracellular metabolic change. The process begins with the binding of specific ligands to receptors located at the surface of the plasma membrane. The receptor responds to the binding of agonists in several different ways.

Signals and Signal Transduction
2018This chapter begins by providing a brief overview of the types of external cues that direct plant growth. In general, an environmental input that initiates one or more plant responses is referred to as a signal, and the physical component that biochemically responds to that signal is designated a receptor.

Calcium and signal transduction
Biochemistry and Molecular Biology Education, 2008AbstractCell signaling is an essential process in which a variety of external signals, defined as first messengers, are translated inside the cells into specific responses, which are mediated by a less numerous group of second messengers. The exchange of signals became a necessity when the transition from monocellular to pluricellular life brought with

Ordered cell proliferation relies on a complex interplay between diverse cell types, interstitial stroma and organ vasculature. At a cellular level the response to growth stimuli is dependent on the bidirectional exchange of information between the cell membrane and nucleus.

Oncogenes and signal transduction
Cell, 1991The purpose of this review is to incorporate recent discoveries into a general biochemical pathway by wich the protein products of the oncogenes send signals from the cell surface to the nucleus .The protein-tyrosine kinase oncogenes will be the primary focus of the review .However, biochemical connections between the protein tyrosine kinases and ...

Recent advances in the study of abscisic acid signal transduction include the identification of cyclic ADP-ribose as a central mediator of abscisic acid responses. The characterisation of type 2C protein phosphatases, ABI1 and ABI2, implicates negative control and redundant action on the signal pathway of this hormone.

Integrins and Signal Transduction
2010Integrin signaling has a critical function in organizing cells in tissues during both embryonic development and tissue repair. Following their binding to the extracellular ligands, the intracellular signaling pathways triggered by integrins are directed to two major functions: organization of the actin cytoskeleton and regulation of cell behaviour ...

Quantitation of signal transduction
The FASEB Journal, 2000Conventional qualitative approaches to signal transduction provide powerful ways to explore the architecture and function of signaling pathways. However, at the level of the complete system, they do not fully depict the interactions between signaling and metabolic pathways and fail to give a manageable overview of the complexity that is often a feature

Regulation of signal transduction
Advances in Enzyme Regulation, 19951. A systematic study is reported on the control of 1-phosphatidylinositol 4-kinase (PI kinase) and PI 4-phosphate 5-kinase (PIP kinase), enzymes of the phosphatidylinositol phosphorylation pathway which leads to the production of second messengers. IP3 and DAG.

Cholesterol in signal transduction
Current Opinion in Cell Biology, 2000Membrane cholesterol impinges on signal transduction in several ways, which is highlighted in particular by the Hedgehog signaling pathway. In Hedgehog signaling, cholesterol is important for ligand biogenesis, as well as for signal transduction in receiving cells.
