Models of ribosome-bound Dom34p and Rli1p and their ribosomal binding partners

Loading... Status: waiting for Mol* initialization Structural highlights 3j16 is a 10 chain structure with sequence from Saccharomyces cerevisiae. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: Electron Microscopy, Resolution 7.2Å Ligands: ATP, MG, SF4 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function DOM34_YEAST Involved in protein translation. Together with HBS1, may function in recognizing stalled ribosomes and triggering endonucleolytic cleavage of the mRNA, a mechanism to release non-functional ribosomes and degrade damaged mRNAs. The complex formed by DOM34 and HBS1 has ribonuclease activity towards double-stranded RNA substrates, but does not cleave single-stranded RNA. Acts as endonuclease; has no exonuclease activity. Increases the affinity of HBS1 for GTP, but nor for GDP. Promotes G1 progression and differentiation and is involved in mitotic and meiotic cell divisions.
