Small nucleolar RNA SNORA40

In molecular biology, the small nucleolar RNA ACA40 belongs to the H/ACA family of snoRNAs and guides the pseudouridylation of 28S rRNA subunit at position U4565. snoRNA ACA40 was discovered using large-scale cloning by Kiss et al. (2004)[1] from a HeLa cell extract immunoprecipitated with an anti-GAR1 antibody. It is predicted to guide the pseudouridylation of residues 28S rRNA U4546 and 18S rRNA 1174.[1][2] The pseudouridylation of these residues was reported by Ofengand and Bakin (1997)[3] and Maden (1990).[4] ACA1, ACA8, ACA18, ACA25, ACA32 and ACA40 and the C/D box snoRNAs mgh28S-2409 and mgh28S-2411 share the same host gene (MGC5306).
