Hinge domain of cleavage stimulation factor subunit 2; The hinge domain of cleavage stimulation factor subunit 2 proteins, CSTF2, is necessary for binding to the subunit CstF-77 within the polyadenylation complex and subsequent nuclear localization. This suggests that nuclear import of a pre-formed CSTF complex is an essential step in polyadenylation. Accurate and efficient polyadenylation is essential for transcriptional termination, nuclear export, translation, and stability of eukaryotic mRNAs. CSTF2 is an important regulatory subunit of the polyadenylation complex.

 81-282 5.86e-05

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.

 353-387 2.06e-03

Partial cleavage stimulation factor domain; Partial_CstF domain is a protein domain that occurs in proteins from apicomplexan parasites. Currently (as of 2012), little is known about the function of this domain. However, it is homologous to the amino-terminal part of the cleavage stimulation factor, which is thought to be involved with mRNA maturation in mammals.
