In molecular biology, the SR1 RNA is a small RNA (sRNA) produced by species of Bacillus and closely related bacteria.[1] It is a dual-function RNA which acts both as a protein-coding RNA and as a regulatory sRNA.
SR1 RNA is involved in the regulation of arginine catabolism. SR1 RNA binds to complementary stretches of ahrC mRNA (also known as argR and inhibits translation.[2][3] AhrC endodes an arginine repressor protein which represses synthesis of arginine biosynthetic enzymes and activates arginine catabolic enzymes via regulation of the rocABC and rocDEF operons.[4][5][6]
In addition to acting as a sRNA, SR1 also encodes a small peptide, SR1P. SR1P binds to glyceraldehyde-3-phosphate dehydrogenase (GapA) and stabilises the gapA operon mRNAs.[7]
