The eIF4 complex is a critical component of the eukaryotic translation initiation machinery, responsible for facilitating the recruitment of ribosomes to the mRNA. It consists of several subunits that each play a specific role in unwinding mRNA secondary structures, stabilizing the mRNA, and interacting with other translation initiation factors to ensure efficient protein synthesis.

Recruitment of ribosomes

Messenger RNA (mRNA) is a type of RNA that carries genetic information from DNA to the ribosome, where proteins are synthesized. It plays a crucial role in the process of gene expression, acting as a template for translating genetic code into functional proteins.

Stabilizing the mRNA

Translation initiation factors are essential proteins that facilitate the beginning of protein synthesis by guiding the ribosome to the correct start codon on messenger RNA. These factors play a critical role in ensuring the accuracy and regulation of protein translation, impacting cellular function and growth.
