Antisense RNA

RNA MOLECULES HYBRIDIZING TO COMPLEMENTARY SEQUENCES IN EITHER RNA OR DAN, ALTERING THE FUNCTION OF THE LATTER

Rna, antisense; Antisense rna; Antisense mRNA; Anti-sense RNA; AsRNA; Antisense gene

Antisense RNA (asRNA), also referred to as antisense transcript, natural antisense transcript (NAT) or antisense oligonucleotide, is a single stranded RNA that is complementary to a protein coding messenger RNA (mRNA) with which it hybridizes, and thereby blocks its translation into protein. asRNAs (which occur naturally) have been found in both prokaryotes and eukaryotes, and can be classified into short (200 nucleotides) non-coding RNAs (ncRNAs).

RNA editing

COVALENT ALTERATION OF ONE OR MORE NUCLEOTIDES WITHIN AN RNA MOLECULE TO PRODUCE AN RNA MOLECULE WITH A SEQUENCE THAT DIFFERS FROM THAT CODED GENETICALLY

RNA Editing; Rna editing; Editosome; RNA modification

RNA editing (also RNA modification) is a molecular process through which some cells can make discrete changes to specific nucleotide sequences within an RNA molecule after it has been generated by RNA polymerase. It occurs in all living organisms and is one of the most evolutionarily conserved properties of RNAs.

RNA-dependent RNA polymerase

ENZYME THAT SYNTHESIZES RNA FROM AN RNA TEMPLATE

RNA replicase; RNA replication; Rna replicase; RNA-directed RNA polymerase; RDRP; RNA-dependent RNA polymerases; Replicase; RNA dependent RNA polymerase; EC 2.7.7.48; Nucleoside-triphosphate:RNA nucleotidyltransferase (RNA-directed); RdRP; Viral replicase; RdRp

RNA-dependent RNA polymerase (RdRp) or RNA replicase is an enzyme that catalyzes the replication of RNA from an RNA template. Specifically, it catalyzes synthesis of the RNA strand complementary to a given RNA template.

OmrA-B RNA

The OmrA-B RNA gene family (also known as SraE RNA, RygA and RygB and OmrA and OmrB) is a pair of homologous OmpR-regulated small non-coding RNA that was discovered in E. coli during two large-scale screens. OmrA-B is highly abundant in stationary phase, but low levels could be detected in exponentially growing cells as well. RygB is adjacent to RygA a closely related RNA. These RNAs bind to the Hfq protein and regulate gene expression by antisense binding. They negatively regulate the expression of several genes encoding outer membrane proteins, including cirA, CsgD, fecA, fepA and ompT by binding in the vicinity of the Shine-Dalgarno sequence, suggesting the control of these targets is dependent on Hfq protein and RNase E. Taken together, these data suggest that OmrA-B participates in the regulation of outer membrane composition, responding to environmental conditions.

Together with the RNA chaperone Hfq, OmrA-B positively controls bacterial motility and negatively controls the production of acidic exopolysaccharide amylovoran in plant pathogen Erwinia amylovora.
