Summary
Eph receptor tyrosine kinases and ephrin ligands form cell communication systems. This review explores how Eph receptors signal through protein complex formation, both with and without ephrin binding.
Area of Science:
- Cellular Biology
- Molecular Biology
- Biochemistry
Background:
- Eph receptor tyrosine kinases (RTKs) and their ephrin ligands are crucial for cell-cell communication.
- This system regulates diverse physiological and pathological processes across various cell types.
Purpose of the Study:
- To review the mechanisms of Eph receptor signaling initiation.
- To focus on protein complex formation in the plasma membrane.
- To explore both ephrin-dependent and independent signaling pathways.
Main Methods:
- Literature review of Eph receptor signaling.
- Analysis of protein complex formation in signaling.
- Examination of intracellular kinase and cell-surface receptor interactions.
Main Results:
- Ephrin binding induces Eph receptor oligomerization and aggregation into large complexes.
- Eph receptors can signal independently of ephrins through interactions with intracellular kinases.
- Eph receptors also interact with other cell-surface receptors for signaling.
- Conserved domain structures contribute to understanding functional differences and redundancies.
Conclusions:
- Eph receptor signaling is complex, involving multiple mechanisms of protein complex formation.
- Understanding these mechanisms is key to deciphering their roles in health and disease.
- Further investigation into Eph receptor signaling complexes is warranted.

5.7K
Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
2.2K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

6.8K
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...

01:11IP3/DAG Signaling Pathway
11.9K
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...

8.3K
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze...

2.0K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
