  Domain Name: IF2_eIF5B
Initiation Factor 2 (IF2)/ eukaryotic Initiation Factor 5B (eIF5B) family. IF2/eIF5B contribute to ribosomal subunit joining and function as GTPases that are maximally activated by the presence of both ribosomal subunits. As seen in other GTPases, IF2/IF5B undergoes conformational changes between its GTP- and GDP-bound states. Eukaryotic IF2/eIF5Bs possess three characteristic segments, including a divergent N-terminal region followed by conserved central and C-terminal segments. This core region is conserved among all known eukaryotic and archaeal IF2/eIF5Bs and eubacterial IF2s.
No pairwise interactions are available for this conserved domain.
