NAPA antisense RNA 1 (NAPA-AS1)

NAPA antisense RNA 1 (NAPA-AS1) is a **long non-coding RNA (lncRNA)** gene located on chromosome 19, transcribed from the NAPA gene locus and found to be expressed in multiple tissues, including the brain, heart, and liver[1]. Its precise biological role is not fully established, but evidence suggests it participates in regulating gene expression, possibly by interacting with proteins involved in transcription and RNA processing[1]. NAPA-AS1's expression levels are dysregulated in various disease states, indicating a potential role in disease mechanisms, though specific links to particular diseases have not yet been conclusively identified[1]. Like other antisense RNAs, NAPA-AS1 may influence gene regulation both at transcriptional and post-transcriptional levels, including modulation of promoter activity, chromatin structure, and RNA maturation[2]. However, there is no evidence currently that NAPA-AS1 itself is a therapeutic target (e.g. not a receptor, enzyme, or transporter), nor are there known drugs that directly interact with it. The gene does not have widely recognized alternative names or abbreviations beyond "NAPA-AS1."[1]
