The eukaryotic initiation factor 3 subunit B (eIF3B) also known as EIF3S9 or p116 plays a central role in the initiation of translation. This protein has a mass of approximately 97 kDa and serves as an important component of the eIF3 complex important for assembling the 40S ribosomal subunit with mRNA and initiator tRNA. eIF3B is ubiquitously expressed in various tissues indicating its fundamental role in cellular protein synthesis.
Biological function summary
EIF3B functions as part of the large eIF3 complex which consists of 13 subunits. This complex is important for the recruitment of mRNA to the 40S ribosomal subunit playing an essential role in the start of translation. eIF3B directly contributes to stabilizing the interaction between mRNA and the ribosome promoting the accurate and efficient formation of the translation initiation complex. This function highlights the importance of eIF3B in regulating cellular protein levels.
Pathways
EIF3B participates in key processes of mRNA translation and is integral to the translation initiation pathway. It interacts with other translation initiation factors including eIF4F and eIF5 orchestrating the assembly and positioning of the ribosome for translation initiation. Moreover eIF3B is also involved in the mTOR signaling pathway linking nutrient sensing to protein synthesis regulation.
EIF3B has been associated with various types of cancer such as breast and prostate cancer where its increased expression correlates with tumor progression and poor prognosis. The dysfunction of eIF3B affects protein synthesis and cell proliferation contributing to oncogenesis. Furthermore eIF3B's role is connected to the dysregulation of mTOR pathways which is significant in cancer development. Its interaction with other proteins like eIF4E and eIF5 signifies its impact on cancer progression pathways.
