C-terminal W2 domain of eukaryotic translation initiation factor 2B epsilon; eIF2B is a heteropentameric complex which functions as a guanine nucleotide exchange factor in the recycling of eIF-2 during the initiation of translation in eukaryotes. The epsilon and gamma subunits are sequence similar and both are essential in yeast. Epsilon appears to be the catalytically active subunit, with gamma enhancing its activity. The C-terminal domain of the eIF2B epsilon subunit contains bipartite motifs rich in acidic and aromatic residues, which are responsible for the interaction with eIF2. The structure of the domain resembles that of a set of concatenated HEAT repeats.

Atrophin-1 family; Atrophin-1 is the protein product of the dentatorubral-pallidoluysian atrophy (DRPLA) gene. DRPLA OMIM:125370 is a progressive neurodegenerative disorder. It is caused by the expansion of a CAG repeat in the DRPLA gene on chromosome 12p. This results in an extended polyglutamine region in atrophin-1, that is thought to confer toxicity to the protein, possibly through altering its interactions with other proteins. The expansion of a CAG repeat is also the underlying defect in six other neurodegenerative disorders, including Huntington's disease. One interaction of expanded polyglutamine repeats that is thought to be pathogenic is that with the short glutamine repeat in the transcriptional coactivator CREB binding protein, CBP. This interaction draws CBP away from its usual nuclear location to the expanded polyglutamine repeat protein aggregates that are characteriztic of the polyglutamine neurodegenerative disorders. This interferes with CBP-mediated transcription and causes cytotoxicity.
