RNA, variant U1 small nuclear 25 (RNVU1-25)

RNA, variant U1 small nuclear 25 (RNVU1-25; LOC124904634) is a human noncoding RNA gene that encodes a variant form of small nuclear RNA closely related to the canonical U1 snRNA[2]. U1 snRNA, both canonical and variant forms, are essential components of the spliceosome, a major ribonucleoprotein complex mediating removal of introns from pre-messenger RNA (pre-mRNA) during the process of splicing[1][3]. Variant U1 snRNAs, including RNVU1-25, are now recognized as transcriptionally active and can be packaged into ribonucleoprotein complexes. They may play important regulatory roles in alternative splicing and mRNA 3′ processing, and can influence gene expression profiles, especially in pluripotent stem cells[1][3]. Emerging evidence suggests that altered variant U1 snRNA expression can disrupt cellular differentiation programs and could be implicated in disease phenotypes such as neurodegenerative disorders, though RNVU1-25 itself is not directly implicated as a disease-causing gene[3]. At present, RNVU1-25 serves as a functional noncoding RNA, not as a canonical drug target or receptor.
