![]() ![]() This partnership establishes an accurate reading frame- ensuring that subsequent codons are correctly deciphered by joining appropriate amino acids to create a functional protein. This specific codon acts as a signal or an invitation for ribosomes and other essential molecules to begin converting the genetic information stored within mRNA into functional proteins. The role of the start codon in protein synthesis is a critical one, as it sets the stage for the entire translation process. Role Of Start Codon In Protein Synthesisĭuring this initial step of translation, initiation factors help recognize and align the start codon with its corresponding tRNA molecule that carries methionine. Understanding how the start codon functions is essential since it lays down each subsequent amino acid in an appropriate sequence – order that ultimately defines a functioning protein’s structure and properties. In eukaryotes, this specific codon always codes for the amino acid methionine, serving as a signal to both initiate translation and determine the correct reading frame for the entire mRNA sequence. The start codon plays a crucial role as the initiation site of protein synthesis, marking the beginning of mRNA translation to build a unique protein sequence. By regulating translation initiation, start codons dictate the amino acid sequence of proteins and ultimately determine their function.Recent advancements, such as ribosome footprint mapping, have shown that eukaryotic organisms may also initiate translation using non-AUG start codons. ![]()
