Eukaryotic translation initiation factor 2 (EIF-2) functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA and binding to a 40S ribosomal subunit. EIF-2 is composed of three subunits, alpha, beta, and gamma, with the protein encoded by this gene representing the beta subunit. The beta subunit catalyzes the exchange of GDP for GTP, which recycles the EIF-2 complex for another round of initiation. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2015]
GeneCards Summary for EIF2S2 Gene
EIF2S2 (Eukaryotic Translation Initiation Factor 2 Subunit Beta) is a Protein Coding gene. Diseases associated with EIF2S2 include leukoencephalopathy with vanishing white matter. Among its related pathways are Gene Expression and Transport to the Golgi and subsequent modification. GO annotations related to this gene include poly(A) RNA binding and translation initiation factor activity.
UniProtKB/Swiss-Prot for EIF2S2 Gene
eIF-2 functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. This complex binds to a 40S ribosomal subunit, followed by mRNA binding to form a 43S preinitiation complex. Junction of the 60S ribosomal subunit to form the 80S initiation complex is preceded by hydrolysis of the GTP bound to eIF-2 and release of an eIF-2-GDP binary complex. In order for eIF-2 to recycle and catalyze another round of initiation, the GDP bound to eIF-2 must exchange with GTP by way of a reaction catalyzed by eIF-2B.
