EIF3M (Eukaryotic Translation Initiation Factor 3 Subunit M): EIF3M is a component of the eukaryotic translation initiation factor 3 (eIF3) complex, which is crucial for protein synthesis. EIF3M plays a vital role in the initiation stage of translation and is important for the overall production of proteins within cells. Alterations in EIF3M can impact cellular growth and proliferation.
