Disease
- Huntington’s disease (HD)
Characteristics
HTTAS is 5'capped, poly (A) tailed and contains three exons, alternatively spliced into HTT-AS1 (exons 1 and 3) and HTT-AS2 (exons 2 and 3)[1].
Expression
HTT-AS1 is expressed in multiple tissues types, with brain and heart expression 2-fold higher than muscle or kidney while is reduced in HD brains.[1].
Function
In cell systems, overexpression of HTT-AS1 specifically reduces endogenous HTT transcript levels, while siRNA knockdown of HTT-AS1 increases HTT transcript levels [1]. HTT-AS1 negatively regulates HTT expression [1]. Repeat length and HTT-AS1 interact to regulate HTT expression [1].
Labs working on this lncRNA
- Department of Psychiatry, Division of Neurobiology, Laboratory of Genetic Neurobiology [1].
