Summary
Tandem-repeat lectins possess inherent multivalency through intrachain repeats, distinct from oligomerization. This systematic review defines and categorizes these lectins, revealing new insights for biotechnological applications.
Area of Science:
- Biochemistry and Structural Biology
- Glycobiology
- Molecular Evolution
Background:
- Multivalency is crucial for lectin function, influencing glycan cross-linking.
- Lectins achieve multivalency via oligomerization or tandemly repeated carbohydrate recognition domains (CRDs).
- Tandem-repeat lectins possess inherent multivalency, independent of complex oligomerization processes.
Purpose of the Study:
- To establish a unified definition for tandem-repeat lectins.
- To systematically review the folding and phyletic diversity of tandem-repeat lectins.
- To explore the functional and structural characteristics of these lectins.
Main Methods:
- Systematic literature review focusing on tandem-repeat lectins.
- Analysis of folding patterns and phyletic distribution.
- Categorization of lectins based on repeated CRDs and associated functions.
Main Results:
- Proposed definition: multivalent lectins with intrachain tandem CRD repeats, independent of oligomerization.
- Identified nine distinct folding classes for tandem-repeat lectins, linked to specific biological functions.
- Discovered previously undocumented tandem-repeat lectins, expanding knowledge of their diversity.
Conclusions:
- Tandem-repeat lectins represent a distinct class of multivalent proteins with inherent structural advantages.
- The proposed classification provides a framework for understanding their diverse functions and evolutionary origins.
- Further research can leverage these findings for medical and biotechnological advancements, including neolectin design.

Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain,...

6.4K
Tandem mass spectrometry, also known as MS/MS or MS2, is an analytical technique that employs two mass analyzers. Essentially it is a series of mass spectrometers that helps isolate a particular biomolecule and then helps study its chemical properties.
This technique helps gather information regarding the protein from which the peptide was obtained and to study the peptides’ amino acid sequence. Identifying peptides from a complex mixture is an important component of the growing field of...

Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

4.8K
Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked. In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence...

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...
