Summary
This review explores the Duffy Antigen Receptor for Chemokines (DARC), a silent receptor involved in malaria and inflammation. Structural modeling and VHH antibodies are discussed for understanding DARC
Area of Science:
- * Molecular biology and immunology.
- * Structural biology and bioinformatics.
- * Infectious diseases and cancer research.
Background:
- * Duffy Antigen Receptor for Chemokines (DARC) is a unique transmembrane chemokine receptor.
- * It binds major chemokine families but lacks signal transduction due to the absence of a DRY consensus sequence, functioning as a silent receptor.
- * DARC plays a significant role in Plasmodium vivax malaria, inflammatory diseases, cancer, and potentially HIV/AIDS.
Purpose of the Study:
- * To review the significance of building structural models of DARC.
- * To understand DARC's binding capabilities with its physiological ligand (CXCL8) and malaria ligand.
- * To present novel developments in VHH antibodies targeting DARC.
Main Methods:
- * Bioinformatic approaches for structural modeling of DARC.
- * Analysis of DARC's interaction with CXCL8 and malaria ligands.
- * Development and application of VHH antibodies against DARC.
Main Results:
- * Structural modeling provides insights into DARC's ligand-binding abilities.
- * VHH antibodies show potential for targeting DARC.
- * Bioinformatic methods face limitations, emphasizing the need for biological data.
Conclusions:
- * Structural modeling of DARC is crucial for understanding its function and interactions.
- * VHH antibodies represent a promising avenue for DARC-targeted research.
- * Integrating bioinformatics with experimental data is essential for advancing DARC research.

01:09Multi-pass Transmembrane Proteins and β-barrels
In multi-pass transmembrane proteins, the polypeptide chain crosses the membrane more than once. The transmembrane polypeptide chain either forms an α-helix or β-strand structure. α-Helix containing multi-pass transmembrane proteins are ubiquitous, whereas β-strand containing ones are mainly found in gram-negative bacteria, mitochondria, and chloroplasts.

01:29Insertion of Multi-pass Transmembrane Proteins in the RER
The rough ER membrane synthesizes, assembles, and embeds transmembrane proteins in diverse topologies. These proteins function as transporters or channels and can remain in the ER membrane or are sent to the Golgi complex, lysosome, and cell membrane.
The multipass transmembrane proteins are the type IV integral membrane proteins with multiple topogenic sequences determining their spatial arrangement in the ER membrane. Nearly all multipass proteins lack a cleavable signal sequence and use...

01:25Single-pass Transmembrane Proteins
Integral membrane proteins are tightly associated with the cell membrane and play a crucial role in cell communication, signaling, adhesion, and transport of the molecules. Some integral membrane proteins are present only in the membrane monolayer. For example, the enzyme fatty acid amide hydrolase is present in the cytoplasmic side of the membrane monolayer. In contrast, another type of integral membrane protein, also known as a transmembrane protein, spans across the membrane. Transmembrane...
01:30Assembly of Signaling Complexes
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.

01:19Membrane Asymmetry Regulating Transporters
Enzymes like flippase, floppase, and scramblase transfer phospholipids from one layer to another in the membrane, thereby affecting membrane asymmetry.
Flippase
Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...

00:59Mechanisms of Membrane Domain Formation
Different physical properties of lipids and proteins allow them to localize and form distinct islands or domains in the membrane. Some membrane domains are formed due to protein-protein interactions, whereas others are formed due to the presence of specific lipids such as sphingolipids and sterols—for example, large proteins, such as bacteriorhodopsin, aggregate and create distinct domains.
Another mechanism for membrane domain formation involves membrane proteins interacting with cytoskeletal...
