Nucleocytoplasmic shuttling protein for mRNA cap-binding EIF4E; EIF4E-T is the transporter protein for shuttling the mRNA cap-binding protein EIF4E protein, targeting it for nuclear import. EIF4E-T contains several key binding domains including two functional leucine-rich NESs (nuclear export signals) between residues 438-447 and 613-638 in the human protein. The other two binding domains are an EIF4E-binding site, between residues 27-42 in Q9EST3, and a bipartite NLS (nuclear localization signals) between 194-211, and these lie in family EIF4E-T_N. EIF4E is the eukaryotic translation initiation factor 4E that is the rate-limiting factor for cap-dependent translation initiation.

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.
