Background:
- Protein post-translational modifications (PTMs) are crucial for cellular signaling.
- Understanding how proteins recognize PTMs is essential for deciphering cellular networks.
- Existing methods for studying PTM-reading domains are limited.
Purpose of the Study:
- To develop a novel chemical probe for identifying and characterizing PTM-reading protein domains.
- To provide a tool for advancing the understanding of molecular signaling pathways.
Main Methods:
- Development of a tri-functional amino acid probe.
- Application of the probe for discovery and characterization of protein domains.
- Utilizing the probe to investigate molecular mechanisms of signaling networks.
Main Results:

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...

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...
