Cell signaling - Wikipedia
In biology, cell signaling (cell signalling in British English) is the process by which a cell interacts with itself, other cells, and the environment. Cell signaling is a fundamental property of all cellular life in prokaryotes and eukaryotes.
Signaling Protein - an overview | ScienceDirect Topics
Signaling proteins, cytokines. The signaling proteins can process information from their immediate environment (outside the cells) or from integration of several simultaneous signals from close or distant cells to produce an action. The signals can be made by chemicals such as hormones or neurotransmitters that act locally or travel to far ...
Signaling Molecules and Their Receptors - The Cell - NCBI …
Some signaling molecules are able to cross the plasma membrane and bind to intracellular receptors in the cytoplasm or nucleus, whereas most bind to receptors expressed on the target cell surface. The sections that follow discuss the major types of signaling molecules and the receptors with which they interact.
Signaling proteins in the spotlight | Science Signaling - AAAS
2016年7月12日 · Advances in technology and the accumulation of proteomic and genomic data reveal previously unknown components of signaling networks, the spatial organization of macromolecular complexes, and how information flows through the networks to produce specific cellular responses.
General Principles of Cell Communication - Molecular Biology of …
Once activated, enzyme- and G-protein-linked receptors relay a signal into the cell interior by activating chains of intracellular signaling proteins; some transduce, amplify, or spread the signal as they relay it, while others integrate signals from different signaling pathways.
Cell Signaling – Fundamentals of Cell Biology
Explain the three stages of a general signaling cascade. Provide examples of common protein families involved in each stage. List and explain the different types of intracellular responses possible for a given signal. Distinguish among relay, amplification, integration, and distribution steps in a signaling cascade.
Signals and Receptors - PMC - PubMed Central (PMC)
Signaling receptors can be single-span plasma membrane receptors associated with tyrosine or serine/threonine kinase activities, proteins with seven transmembrane domains, or intracellular receptors.
Signaling Protein - an overview | ScienceDirect Topics
Signaling proteins are flexible in both form and function. They can bind to multiple molecular partners and integrate diverse types of cellular information. When imaged by time-lapse microscopy, many signaling proteins show complex patterns of activity or …
Intracellular signalling peptides and proteins - Nature
2024年11月28日 · Intracellular signalling peptides and proteins are peptides and proteins involved in transmission of signals (signal transduction) across the membrane of cells.
Conceptual Evolution of Cell Signaling - PMC
Signaling specificity of a protein often arises from its domain structure. A domain is a distinctly folded part of a protein that imparts particular functions and allows it to differentially engage in signaling pathways. Proteins that are functionally alike can have distinct domains and vice versa.
