Small Cajal body specific RNA 25

Small Cajal body specific RNA 25 (otherwise known as scaRNA25, HBI-100, MBI-100 and MBI-114) is a scaRNA which are a class of ncRNAs characterised as a small nuclear RNAs localised to the Cajal bodies. ScaRNA25 was originally identified in a large scale cloning project in mouse. Later sequence analysis predicted that this RNA guides the pseudouridylation of position U40 in the U6 snRNA.
