Activity summary

EIF3F also known as eukaryotic translation initiation factor 3 subunit F is a critical component in the initiation of mRNA translation. The molecular weight of EIF3F is approximately 42 kDa. This protein is expressed in various tissues with a higher presence in rapidly dividing cells such as those in the liver and testes. EIF3F plays a mechanical role in the recruitment and assembly of other initiation factors and ribosomal units facilitating the proper positioning of the mRNA on the ribosome.

Biological function summary

EIF3F contributes to the regulation of protein synthesis by being part of the EIF3 complex which is essential for translation initiation. This complex interacts with several other initiation factors to ensure efficient ribosomal translation of mRNA into proteins. EIF3F is involved in maintaining the balance between global protein synthesis and selective translation thereby influencing cell growth and proliferation. Its interaction with ribosomal RNA and other initiation factors helps in stabilizing the pre-initiation complex.

Pathways

EIF3F is integral to the mTOR signaling pathway and the endoplasmic reticulum (ER) stress response pathway. These pathways are central to cellular responses to nutrient availability and misfolded proteins respectively. The mTOR pathway involves EIF3F in regulating cell growth and autophagy through its interaction with other proteins like TSC1/2. In the ER stress response EIF3F works alongside proteins such as ATF4 to control protein synthesis rates during stress conditions.

Associated diseases and disorders

EIF3F shows associations with cancer and neurodegenerative diseases. In cancer aberrant EIF3F expression can lead to uncontrolled cell growth and tumor formation particularly noted in liver and prostate cancers. It interacts frequently with proteins like c-Myc which are key in oncogenic pathways. In neurodegenerative conditions disruptions in EIF3F and related proteins can affect neural cell survival with links observed in disorders such as amyotrophic lateral sclerosis (ALS). The disruption in EIF3F's role in protein synthesis pathways may contribute to neuronal damage and disease progression.
