Small nucleolar RNA MBI-28, also known as SNORA3 and ACA3, is a non-coding RNA (ncRNA) molecule which functions in the biogenesis (modification) of other small nuclear RNAs (snRNAs). This type of modifiying RNA is located in the nucleolus of the eukaryotic cell which is a major site of snRNA biogenesis. It is known as a small nucleolar RNA (snoRNA) and also often referred to as a 'guide RNA'.^[1]

snoRNA MBI-28 was originally cloned from mouse brain tissues^[2] and belongs to the H/ACA box class of snoRNAs as it has the predicted hairpin-hinge-hairpin-tail structure and has the conserved H/ACA-box motifs.
