Abstract

Eukaryotic protein synthesis initiation factor eIF2B is the essential guanine-nucleotide exchange factor for eIF2. eIF2B is known to regulate protein synthesis in response to cellular stresses. We will characterise a novel regulator of eIF2B (termed SIF1) that specifically suppresses the eIF2B catalytic defect of yeast eIF2B mutations but does not alter the previously characterised response of eIF2B to amino acid starvation. The priorities are: 1) To clone the SIF1 gene by complementation using a yeast genetic screen. 2) Biochemical analysis of the effects of the sif1 mutation on eIF2B activity in vitro. 3) Genetic and biochemical experiments using modern molecular tools to determine the function of SIF1 in translation initiation.
