Splicing errors in protein synthesis
Web8 Oct 2024 · Protein synthesis initiation is triggered by the presence of several initiation factors IF1, IF2, and IF3, including mRNA, ribosomes, tRNA. The small subunit binds to the upstream on the 5′ end at the start of mRNA. The ribosome scans the mRNA in the 5′ to 3′ direction until it encounters the start codon (AUG or GUG or UUG). Web2 Feb 2012 · This means that a cell can produce lots of copies of the same protein from a single mRNA molecule. Post-Translational Modifications Sometimes a protein needs some help to fold into its required tertiary structure. Modifications can be made after translation by enzymes such as methylation, phosphorylation, and glycosylation.
