receptormediator
Receptormediator is a term used in cell signaling discussions to describe adaptor or mediator proteins and factors that connect receptor activation to intracellular signaling cascades. The concept emphasizes the bridging role these molecules play between an activated receptor and downstream effectors, shaping the amplitude, duration, and specificity of the response. Receptormediators are typically recruited to phosphorylated receptors or membrane subdomains through modular interaction domains and may assemble signaling complexes that include kinases, phosphatases, and transcriptional regulators.
In practice, several well-characterized adapters and scaffolds fulfill receptive mediator roles. For receptor tyrosine kinases, proteins
The term is not a formal taxonomic class in most databases; rather, it is a descriptive label
