Quantitative Rps2 BioID to monitor Asc1-dependent rearrangement at the head region of the 40S ribosome

ABSTRACT: In a previous study we applied a quantitative proximity-labeling technique called Biotin Identification (BioID, Roux et al., 2012) to analyze the microenvironment of the Gβ-like scaffold protein Asc1 (Opitz et al., 2017). The WD40-repeat protein Asc1 binds to the head region of the small 40S ribosomal (hr40S) subunit. In this study, we analyzed the hr40S from the perspective of Rps2, a ribosomal neighbor of Asc1. We intended to confirm proteins of the Asc1 proxiOME at the hr40S and to observe changes when Asc1 was absent. References: Roux K.J., Kim D.I., Raida M., Burke B. 2012.
