Summary
Cell surface receptors bind extracellular messengers, but only activated receptors transmit signals. Advances reveal molecular mechanisms behind receptor activation, signal generation, and transmembrane signal transfer.
Area of Science:
- Cellular biology
- Molecular signaling
- Biochemistry
Background:
- Extracellular messengers interact with cell surface receptors.
- Ligand binding does not always lead to receptor activation.
- Activated receptors initiate intracellular signaling cascades.
Purpose of the Study:
- To explore molecular mechanisms of receptor activation.
- To understand signal generation following receptor activation.
- To elucidate transmembrane signal transfer processes.
Main Methods:
- Review of recent advances in receptor activation studies.
- Analysis of molecular mechanisms.
- Integration of findings on signal transduction.
Main Results:
- Identified distinct pathways for agonist-induced and constitutive receptor activation.
- Elucidated mechanisms of signal generation.
- Described processes of transmembrane signal transfer.
Conclusions:
- Receptor activation is a critical step in cellular communication.
- Understanding these mechanisms is key to deciphering cellular responses.
- Further research can reveal therapeutic targets for signaling disorders.

01:21Cell-surface Signaling
Hormones—or any molecule that binds to a receptor, known as a ligand—that are lipid-insoluble (water-soluble) are not able to diffuse across the cell membrane. In order to be able to affect a cell without entering it, these hormones bind to receptors on the cell membrane. When a first messenger, a hormone, binds to a receptor, a signal cascade is set off, causing second messengers, proteins inside the cell, to become activated, resulting in downstream effects.
01:26Secondary Messengers in Hormone Action
Water-soluble hormones cannot cross the plasma membrane, so they rely on protein receptors that span the membrane to trigger intracellular signaling pathways. These pathways then activate second messengers inside the cell, including cAMP or calcium ions.
Many hormones bind to transmembrane G protein-coupled receptors that connect to regulatory G proteins. These G proteins can then activate enzymes such as adenylyl cyclase or phospholipase C. Adenylyl cyclase converts ATP to cAMP, activating...

01:15Amplifying Signals via Second Messengers
Many receptor binding ligands are hydrophilic; they do not cross the cell membrane but bind to cell-surface receptors. Thus, their message must be relayed by second messengers present in the cell cytoplasm. There are several second messenger pathways, each with its own way of relaying information. For example, the G protein-coupled receptors can activate both phosphoinositol and cyclic AMP (cAMP) second messenger pathways. The phosphoinositol pathway is active when the receptor induces...
01:28Types of Receptors: Cell Surface Receptors
Cell-surface receptors, also known as transmembrane receptors, are cell surface, membrane-anchored (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. Ligands that interact with cell-surface receptors do not have to enter the cell that they affect. Cell-surface receptors are also called cell-specific proteins or markers because they are...
01:11IP3/DAG Signaling Pathway
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and produces two-second...
01:00Enzyme-linked Receptors
Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...
