Summary
Integrins are cell adhesion proteins that require activation. This review explores how phosphorylation regulates leukocyte-specific β2-integrins, impacting cellular signaling and adhesion.
Area of Science:
- Cellular Biology
- Immunology
- Biochemistry
Background:
- Integrins are type I membrane proteins crucial for cell adhesion and signaling.
- These proteins are typically inactive in resting cells and require activation for adhesive functions.
- While integrin structure and interactions are well-studied, their regulatory mechanisms remain incompletely understood.
Purpose of the Study:
- To review the role of integrin phosphorylation in regulating the activity of leukocyte-specific β2-integrins.
- To highlight how phosphorylation enables rapid and localized control of integrin function in leukocytes.
Main Methods:
- Literature review focusing on leukocyte-specific β2-integrins.
- Analysis of existing research on integrin phosphorylation and its functional consequences.
Main Results:
- Phosphorylation is a key mechanism for regulating integrin activity.
- This process allows for rapid and reversible control of integrin function.
- Specific phosphorylation events enable precise temporal and spatial regulation of β2-integrins in leukocytes.
Conclusions:
- Integrin phosphorylation is critical for modulating leukocyte adhesion and signaling.
- Understanding these regulatory pathways is essential for comprehending leukocyte function in immunity and inflammation.
- Targeting integrin phosphorylation may offer therapeutic strategies for immune-related diseases.

2.7K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

4.3K
Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...

Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...

01:22Amplifying Signals via Enzymatic Cascade
15.1K
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...

7.6K
Phosphoinositides are a group of phospholipids containing a glycerol backbone with two fatty acid chains and a phosphate attached to a myoinositol sugar ring. The inositol head group extends into the cytoplasm, where it is modified by adding phosphate groups to form phosphatidylinositol phosphates or PIPs.
Different phosphoinositides are synthesized and recruited on the cytosolic face of the plasma membrane. The localization of specific phosphoinositides concentrated in separate membrane...

Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.
