biostudies-literatureUnknown6Schein AMammalian genomes encode numerous natural antisense long noncoding RNAs (lncRNAs) that regulate gene expression. Recently, an antisense lncRNA to mouse Ubiquitin carboxyl-terminal hydrolase L1 (Uchl1) was reported to increase UCHL1 protein synthesis, representing a new functional class of lncRNAs, designated as SINEUPs, for SINE element-containing translation UP-regulators. Here, we show that an antisense lncRNA to the human protein phosphatase 1 regulatory subunit 12A (PPP1R12A), named as R12A-AS1, which overlaps with the 5' UTR and first coding exon of the PPP1R12A mRNA, functions as a SINEUP, increasing PPP1R12A protein translation in human cells. The SINEUP activity depends on the aforementioned sense-antisense interaction and a free right Alu monomer repeat element at the 3' end of R1Scientific reports33605https://www.ebi.ac.uk/biostudies/studies/S-EPMC5028707biostudies-literatureIdentification of antisense long noncoding RNAs that function as SINEUPs in human cells.PMC5028707Schein AKauppinen SCarninci PGustincich SZucchelli SfalseIdentification of antisense long noncoding RNAs that function as SINEUPs in human cells.Mammalian genomes encode numerous natural antisense long noncoding RNAs (lncRNAs) that regulate gene expression.
