Functions of Cell Surface Receptors - The Cell - NCBI Bookshelf
G Protein-Coupled Receptors. The largest family of cell surface receptors transmit signals to intracellular targets via the intermediary action of guanine nucleotide-binding proteins called G proteins.
Types of Receptors - Biology LibreTexts
2024年11月23日 · Cell-surface receptors, also known as transmembrane receptors, are cell surface, membrane-anchored, or integral proteins that bind to external ligand molecules. This type of receptor spans the plasma membrane and performs signal transduction, converting an extracellular signal into an intracellular signal.

2024年9月19日 · Cell-surface receptors are transmembrane proteins embedded in the plasma membrane of target cells. These receptors consist of an extracellular domain containing the ligand-binding site, a transmembrane domain, and an …
7.2: Types of Receptors - Biology LibreTexts
Cell-surface receptors, also known as transmembrane receptors, are proteins that are found attached to the cell membrane. These receptors bind to external ligand molecules (ligands that do not travel across the cell membrane).
Cell Surface Receptors and Their Signal Transduction Pathways
The RTK-Ras pathway begins at the cell surface, where a receptor tyrosine kinase (RTK) binds its specific ligand. Ligands that bind to RTKs include the fibroblast growth factors, epidermal growth factors, platelet-derived growth factors, and stem cell factor.
Signals and Receptors - PMC - PubMed Central (PMC)
Integrins are perhaps the best known cell-surface receptors involved in these essential processes. They function primarily in cell adhesion to the extracellular matrix (ECM) or to other cells, the latter through a repertoire of cell-surface ligands involved in cell–cell interactions.
G protein-coupled receptors (GPCRs): advances in structures, …
2024年4月10日 · G protein-coupled receptors (GPCRs) are the largest superfamily of cell surface membrane receptors and are encoded by approximately 1000 genes, sharing conserved seven-transmembrane (7TM)...

2024年4月8日 · There are three main types of cell surface receptors: ion channel receptors, G-protein coupled receptors (GPCRs) and enzyme-linked receptors. While these each have unique structures, cell surface receptors are generally composed of three domains: an extracellular ligand-binding domain, a hydrophobic domain embedded within the plasma membrane ...
