These related snoRNAs are predicted to belong to the C/D box class of snoRNAs which contain the conserved sequence motifs known as the C box (UGAUGA) and the D box (CUGA).
SnoRNAs that exhibit relationships with other snoRNAs in this category are expected to possess the characteristic C/D box motifs, including the repeating sequences UGAUGA for the C box and CUGA for the D box.
