Abstract:
Studying protein-protein interactions is critical to our understanding of signaling pathways. Telomere Interactome is assembled around telomeres and consists of proteins and factors from diverse pathways. Dissecting how this protein network contributes to telomere protection and length regulation requires the elucidation of the complex and dynamic interactions between the proteins within the interactome. Here, we focus on three assays, Bi-molecular Fluorescence Complementation (BiFC), Gaussia Luciferase Protein-fragment Complementation Assay (GLuc PCA), and OPAL peptide array, which have proven vital in our studies of telomere protein interaction networks.
