Eukaryotic Initiation Factor 6 (EIF6), also known as ITGB4BP or p27BBP, is a conserved protein critical for ribosome biogenesis and translational regulation. Structurally, it is a 27 kDa protein containing an N-terminal charged region and a C-terminal oligonucleotide-binding fold. EIF6 binds to the 60S ribosomal subunit, preventing premature association with the 40S subunit during ribosome assembly. This "anti-association" activity ensures proper maturation and nucleocytoplasmic transport of pre-60S particles.
Beyond its canonical role, EIF6 interacts with multiple signaling pathways. It modulates insulin/mTOR signaling through direct binding to the β4 integrin cytoplasmic domain, linking cellular adhesion to translational control. Dysregulation of EIF6 expression correlates with pathological conditions—its overexpression is implicated in cancer progression (e.g., breast cancer and lymphoma) by enhancing ribosome production and cell proliferation, while reduced levels associate with metabolic disorders like diabetes mellitus. Notably, EIF6 haploinsufficiency in mice induces insulin resistance, highlighting its metabolic regulatory functions.
Recombinant EIF6 proteins are typically produced in bacterial (E. coli) or mammalian expression systems. The purified protein serves as an essential tool for structural studies, including X-ray crystallography and cryo-EM analyses that revealed its interaction interfaces with ribosomes and other partners. Functional applications range from in vitro translation assays to drug discovery platforms targeting ribosome biogenesis in oncology. Recent studies also explore EIF6's potential as a biomarker in liquid biopsies, given its extracellular release from stressed cells. Current research focuses on developing EIF6-targeted therapies, particularly small-molecule inhibitors that could disrupt its oncogenic functions while preserving essential ribosomal activities.
