The eukaryotic translation initiation factor 5 (EIF5) plays an important role in the initiation phase of protein synthesis. EIF5 also known as eIF-5 is a protein that exhibits a molecular weight of approximately 49 kDa. It functions as a GTPase-activating protein that triggers the hydrolysis of GTP bound to the eukaryotic initiation factor 2 (eIF2) an essential step for the formation of the 80S ribosome complex during translation. EIF5 expression occurs widely across various tissues indicating its necessity for basic cellular functions.

Biological function summary

EIF5 facilitates the translation initiation process which is critical for protein synthesis. It is an integral component of the multifactor eIF2 complex that ensures the accuracy of start codon recognition in mRNA. This complex assembly involves the association with other initiation factors like eIF1 and eIF3 orchestrating mRNA scanning and the selection of the start site for protein synthesis. EIF5's role in regulating protein biosynthesis links it to the maintenance of cellular homeostasis.

Pathways

EIF5 serves a critical part in the translation initiation pathway. This pathway is essential for general protein biosynthesis directly impacting cellular growth and proliferation. It closely collaborates with related factors like eIF2 and eIF2B within this pathway to modulate translation in response to cellular stress and nutrient availability. Additionally EIF5 intersects the mTOR signaling pathway where it interacts with proteins that coordinate cell growth and metabolism under various physiological conditions.

EIF5 alterations can lead to disruptions in protein synthesis connecting it to certain human diseases like cancer. Some studies indicate a link between EIF5 dysregulation and tumorigenesis as faults in translation regulation can drive abnormal cell proliferation. Beyond cancer EIF5 may also intersect with neurodegenerative diseases given the translation regulation's importance in neuronal function. It can associate with other factors such as eIF2α wherein heightened EIF5 activity influences stress responses pivotal in disease contexts.

ターゲットの情報

Component of the 43S pre-initiation complex (43S PIC), which binds to the mRNA cap-proximal region, scans mRNA 5'-untranslated region, and locates the initiation codon (PubMed : 11166181, PubMed : 22813744, PubMed : 24319994). In this complex, acts as a GTPase-activating protein, by promoting GTP hydrolysis by eIF2G (EIF2S3) (PubMed : 11166181). During scanning, interacts with both EIF1 (via its C-terminal domain (CTD)) and EIF1A (via its NTD) (PubMed : 22813744). This interaction with EIF1A contributes to the maintenance of EIF1 within the open 43S PIC (PubMed : 24319994). When start codon is recognized, EIF5, via its NTD, induces eIF2G (EIF2S3) to hydrolyze the GTP (PubMed : 11166181). Start codon recognition also induces a conformational change of the PIC to a closed state (PubMed : 22813744). This change increases the affinity of EIF5-CTD for EIF2-beta (EIF2S2), which allows the release, by an indirect mechanism, of EIF1 from the PIC (PubMed : 22813744). Finally, EIF5 stabilizes the PIC in its closed conformation (PubMed : 22813744).
