Suppressor of clathrin deficiency (Scd6)-An emerging RGG-motif translation repressor

Suppressor of clathrin deficiency (Scd6)-An emerging RGG-motif translation repressor

Wiley Interdisciplinary Reviews. Rna 2018: E1479

Translation control plays a key role in variety of cellular processes. Translation initiation factors augment translation, whereas translation repressor proteins inhibit translation. Different repressors act by distinct mechanisms to accomplish the repression process. Although messenger RNAs (mRNAs) can be repressed at various steps of translation, most repressors have been reported to target the initiation step. We focus on one such translation repressor, an Arginine-Glycine-Glycine (RGG)-motif containing protein Scd6. Using this protein as a model, we present a discourse on the known and possible functions of this repressor, its mechanism of action and its recently reported regulation. We suggest a case for conservation of the mechanism employed by Scd6 along with its regulation in orthologs, and propose that Scd6 family of proteins will be an ideal tool to understand translation control and mRNA fate decision mechanisms across biological systems.
