HTT antisense RNA (head to head)
HTTAS_v1 expression.(A and B) Relative expression level of HTTAS_v1 in multiple human tissues and brain regions. (C) Genomic region 5′ to the HTTAS_v1 transcription start site. (D) HTTAS_v1 promoter activity in HEK293 cells. (E) Promoter activity is increased by a short repeat, but is reduced by repeat expansion. [1].

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, and this effect is dependent on repeat length of HTT-AS1 [1].
