Summary
Marine invertebrates inspire new underwater adhesives. Researchers identified glycoproteins and a novel Nectin variant in sea urchin tube feet, advancing bioadhesive technology.
Area of Science:
- Biomaterials Science
- Marine Biology
- Biochemistry
Background:
- Biomedical adhesives struggle with wet adhesion.
- Marine invertebrate adhesives offer water resistance, nontoxicity, and biodegradability.
- Sea urchin tube feet secrete a complex adhesive.
Purpose of the Study:
- Investigate glycosylation of sea urchin adhesive protein candidates.
- Identify specific glycoproteins involved in adhesion.
- Characterize novel adhesion-related proteins in *Paracentrotus lividus*.
Main Methods:
- Lectin pulldowns to identify glycoproteins.
- Mass spectrometry for protein identification.
- In silico analysis for protein characterization.
Main Results:
- At least five previously identified adhesive/cohesive protein candidates are glycoproteins.
- A third Nectin variant, an adhesion-related protein, was identified.
- Detailed characterization of adhesive glycoproteins was achieved.
Conclusions:
- Identified key glycoproteins and a novel Nectin variant in sea urchin adhesive.
- This research provides insights for developing advanced sea urchin-inspired bioadhesives.
- Understanding these components is crucial for replicating natural adhesive properties.

3.4K
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,...

01:03Anchoring Junctions
3.9K
Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...

01:17Intracellular Signaling Affects Focal Adhesions
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.

01:31Immunoglobulin-like Cell Adhesion Molecules
3.3K
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

01:24Adherens Junctions
4.9K
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

2.8K
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.
Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose,...
