Summary
Researchers identified shell proteins in marine brachiopods using proteomics. These brachiopod shell proteins differ from those found in other calcifying marine invertebrates, offering insights for biomaterials.
Area of Science:
- Marine Biology
- Biomineralization
- Proteomics
Background:
- Brachiopods are marine invertebrates with calcite shells containing organic matrix proteins.
- These proteins are crucial for controlling mineral deposition and crystal shape in shells.
- Understanding shell matrix proteins is key for developing bioinspired materials.
Purpose of the Study:
- To identify peptides constituting shell proteins in three rhynchonellid brachiopod species.
- To compare brachiopod shell proteomes with those of other calcifying organisms.
Main Methods:
- Proteomic analysis was used to identify shell proteins.
- Samples were collected from three different brachiopod species.
Main Results:
- Numerous shell protein peptides were identified in the studied brachiopods.
- The identified shell protein repertoires differ significantly from those of molluscs.
Conclusions:
- The proteomic data provides a foundation for understanding brachiopod shell formation.
- Brachiopod shell matrix proteins represent a distinct evolutionary path compared to other calcifiers.
- This research aids in the design of novel biomimetic materials.

Diversity of Protists III
2.1K
Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Ribosome Profiling
4.3K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

Proteomics
10.2K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Archaeal surface appendages are highly specialized structures essential for environmental adaptation, encompassing roles in adhesion, biofilm formation, and motility. Among these appendages, pili and archaella stand out for their distinct morphologies and functionalities, enabling archaea to thrive in diverse and often extreme environments.Pili: Adhesion and Biofilm FormationPili are filamentous structures assembled from pilin protein subunits, primarily contributing to adhesion and biofilm...

Channel Rhodopsins
3.5K
Most organisms use photoreceptors to sense and respond to light. Examples of photoreceptors include bacteriorhodopsins and bacteriophytochromes in some bacteria, phytochromes in plants, and rhodopsins in the photoreceptor cells of the vertebral retina. The light-sensitive property of these receptors is because of the bound chromophores, such as bilin in the phytochromes and retinal in the rhodopsins.
Rhodopsins belong to the family of cell surface proteins called G-protein coupled receptors,...

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...
