Identification of Insulin-Activated Rab Proteins in Adipose Cells Using Bio-ATB-GTP Photolabeling Technique

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

We have recently developed a photolabeling method to identify GTP-loaded Rab proteins. The new biotinylated GTP analogue (Bio-ATB-GTP) binds to GTP-binding proteins and after a UV irradiation a covalent bond is formed between the protein and the photoreactive diazirine group on the photolabel. The tagged protein can then be isolated and detected using the classic biotin-streptavidin interaction. In this chapter, we describe the Bio-ATB-GTP photolabel and discuss the advantages of using this photolabeling approach to detect GTP-loaded Rab proteins compared to other existing methodologies. We also describe a step-by-step procedure for detecting the activated state of a Rab protein in primary rat adipocytes.
