Long intergenic non-protein coding RNA 1431 (LINC01431)

Long intergenic non-protein coding RNA 1431 (LINC01431) is a long intergenic non-coding RNA gene that encodes a nuclear non-coding RNA molecule involved in the regulation of epigenetic cellular processes, particularly histone modification. LINC01431 does not code for a protein and functions through interactions with protein partners such as PRMT1, enhancing its stability and promoting histone H4 arginine 3 methylation (H4R3me2a), leading to transcriptional repression of hepatitis B virus (HBV) covalently closed circular DNA (cccDNA)[2][4]. LINC01431 activity impedes HBV replication and modulates the accessibility of viral DNA to transcriptional machinery. This lincRNA exemplifies a broader class of non-coding RNAs involved in fine-tuning gene expression and epigenetic landscapes, with emerging roles in infection and cancer biology[2][4][5]. Based on current literature and gene database entries, LINC01431 is not classified as a traditional therapeutic target (e.g., enzyme, receptor, transporter), and there are no validated drugs or direct clinical biomarkers associated with it[1][2][4].

Not directly targeted by drugs but acts as a scaffold for regulating protein arginine methyltransferase 1 (PRMT1), affecting histone methylation and viral chromatin silencing[2][4].
