EIF2S2 (eukaryotic translation initiation factor 2 subunit beta)

Gene

• Entrez ID: 8894
• Gene name: Eukaryotic translation initiation factor 2 subunit beta
• Gene symbol: EIF2S2
• Synonyms (NCBI Gene): EIF2, EIF2B, EIF2beta, PPP1R67, eIF-2-beta
• Chromosome: 20
• Chromosome location: 20q11.22
• Summary: 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 gam
