Area of Science:
- Proteomics
- Molecular Biology
- Plant Science
Background:
- Post-translational modifications (PTMs) increase protein complexity and regulate biological events.
- Global identification of PTMs is challenging, requiring advanced proteomics techniques.
- Proteins often undergo prefractionation to reduce complexity and enrich modified forms for analysis.
Purpose of the Study:
- To review post-translational modification (PTM) studies in plants.
- To describe the sample preparation strategies used in these plant PTM studies.
Main Methods:
- Affinity-based enrichment methods.
- Immobilized metal affinity chromatography (IMAC).
- Immunoprecipitation (IP).
- Phase partitioning.
Main Results:
- Summarizes PTM studies in plants.
- Details sample preparation strategies for phosphorylation, ubiquitination, and glycosylphosphatidylinositol (GPI) modifications.
- Highlights the application of IMAC and IP for specific PTM enrichment.
Conclusions:

01:33Proteomics
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 proteomics...

01:25Cell Signaling in Plants
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...
