This entry represents the helical bundle domain found within the C-terminal dimerization domain of Elongator complex protein 1 (ELP1), from eukaryotes. Elongator is a conserved protein complex implicated in multiple processes including regulation of transcription, alpha-tubulin acetylation and tRNA modification. Mutations in the ELP1 gene have been shown to cause the neurodegenerative disease familial dysautonomia [1]. The C-terminal dimerization domain consists of 28 alpha-helices organised in three domains: an elongated alpha-solenoid domain (helices 1 to 14); a TPR domain, formed by six double-helix repeats (helices 15 to 26); and a three-helix bundle, C-terminal cap (helices 26 to 28) [2]. ELP1 self-association contributes to its stability and is important for Elongator assembly [2]. ELP1 is considered to function both as a scaffold, for Elongator complex ELP2 and ELP3 binding, and as a docking site for various factors that regulate Elongator activity [2-4]. Also known as IKAP, ELP1 acts as a regulator of IkB kinase complex involved in proinflammatory cytokine signalling [5].
