Summaries for ATN1 Gene

Entrez Gene Summary for ATN1 Gene

  • Dentatorubral pallidoluysian atrophy (DRPLA) is a rare neurodegenerative disorder characterized by cerebellar ataxia, myoclonic epilepsy, choreoathetosis, and dementia. The disorder is related to the expansion from 7-35 copies to 49-93 copies of a trinucleotide repeat (CAG/CAA) within this gene. The encoded protein includes a serine repeat and a region of alternating acidic and basic amino acids, as well as the variable glutamine repeat. Alternative splicing results in two transcripts variants that encode the same protein. [provided by RefSeq, Jul 2016]

GeneCards Summary for ATN1 Gene

ATN1 (Atrophin 1) is a Protein Coding gene. Diseases associated with ATN1 include Dentatorubro-Pallidoluysian Atrophy and Spinocerebellar Ataxia 1. GO annotations related to this gene include protein domain specific binding. An important paralog of this gene is RERE.

UniProtKB/Swiss-Prot for ATN1 Gene

  • Transcriptional corepressor. Recruits NR2E1 to repress transcription. Promotes vascular smooth cell (VSMC) migration and orientation (By similarity). Corepressor of MTG8 transcriptional repression. Has some intrinsic repression activity which is independent of the number of poly-Asn (polyQ) repeats.

neXtProt entry for ATN1 Gene

Post-translational modifications for ATN1 Gene

  • Phosphorylated in vitro by MAPK8/JNK1 on Ser-739. Mutant ATN1 sequences with expanded poly-Asn (polyQ) traits are more slowly phosphorylated.
  • Proteolytically cleaved, probably in the nucleus, to produce two C-terminal fragments of 140 kDa (F1) and 125 kDa (F2) each containing poly-Asn (polyQ) tracts. F2 is produced by cleavage by caspases and is exported into the cytoplasm. In vitro, cleavage increases with an increase in the number of polyQ tracts. C-terminal proteolytic products appear to be the cause of cell toxicity. In vitro cleavage at Asp-109.
  • Ubiquitination at Lys947
  • Modification sites at PhosphoSitePlus
