TB6Cs1H4 is a member of the H/ACA-like class of non-coding RNA (ncRNA) molecule that guide the sites of modification of uridines to pseudouridines of substrate RNAs. It is known as a small nucleolar RNA (snoRNA) thus named because of its cellular localization in the nucleolus of the eukaryotic cell. TB6Cs1H4 is predicted to guide the pseudouridylation of LSU5 ribosomal RNA (rRNA) at residue Ψ824.
