EIF2B1 also known as eukaryotic translation initiation factor 2B subunit alpha functions mechanically as a regulatory subunit in the eIF2B complex. This protein has a mass of approximately 38 kDa. EIF2B1 is expressed in various tissues throughout the body including the brain heart liver and muscle. It plays a critical role in protein synthesis by regulating the exchange of GDP for GTP on the eIF2 protein which is essential for initiating translation.

Biological function summary

EIF2B1 regulates protein synthesis by modulating the activity of the eIF2B complex which is a guanine nucleotide exchange factor. This complex comprises five subunits and EIF2B1 is integral for its function. Through regulation of eIF2 EIF2B1 indirectly controls the rate of translation initiation affecting cell growth and stress response mechanisms. In neurons EIF2B1’s activity influences neuronal development and maintenance.

Pathways

EIF2B1 functions prominently in both the unfolded protein response and integrated stress response pathways. These pathways respond to cellular stress by altering translation rates and are essential for maintaining protein homeostasis. EIF2B1 interacts primarily through these pathways with other proteins such as eIF2 and ATF4 which is a transcription factor activated during stress responses.

EIF2B1 plays a significant role in disorders like Vanishing White Matter (VWM) disease. Mutations in the EIF2B1 gene can lead to VWM a genetic condition affecting the central nervous system and presenting symptoms such as ataxia and neurological deterioration. Additionally disruption of EIF2B1 function relates to stress-related disorders due to its role in stress response pathways. Through these pathways EIF2B1 associates with proteins like eIF2 which can also affect susceptibility to stress disorders.

Target data

Acts as a component of the translation initiation factor 2B (eIF2B) complex, which catalyzes the exchange of GDP for GTP on eukaryotic initiation factor 2 (eIF2) gamma subunit (PubMed : 25858979, PubMed : 27023709, PubMed : 31048492). Its guanine nucleotide exchange factor activity is repressed when bound to eIF2 complex phosphorylated on the alpha subunit, thereby limiting the amount of methionyl-initiator methionine tRNA available to the ribosome and consequently global translation is repressed (PubMed : 25858979, PubMed : 31048492).
