GeneCards Summary for SNORA2B Gene
SNORA2B (Small Nucleolar RNA, H/ACA Box 2B) is an RNA Gene, and is affiliated with the snoRNA class.
fRNAdb sequence ontologies for SNORA2B Gene - the ORGUL cluster for this gene includes several descriptions:
H_ACA_box_snoRNA: Members of the box H/ACA family contain an ACA triplet, exactly 3 nt upstream from the 3' end and an H-box in a hinge region that links two structurally similar functional domains of the molecule. Both boxes are important for snoRNA biosynthesis and function. A few box H/ACA snoRNAs are involved in rRNA processing; most others are known or predicted to participate in selection of uridine nucleosides in rRNA to be converted to pseudouridines. Site selection is mediated by direct base pairing of the snoRNA with rRNA through one or both targeting domains.
nc_conserved_region: Non-coding region of sequence similarity by descent from a common ancestor.
Small nucleolar RNA SNORA2/SNORA34 family: The members of this family belong to the H/ACA class of snoRNAs which are predicted to guide the sites of modification of uridines to pseudouridines . This family includes human snoRNAs ACA2a (SNORA2A), ACA2b (SNORA2B) and ACA34 (SNORA34). ACA2a and ACA2a are predicted to guide pseudouridylation of U4263 and U4282 in 28S rRNA and ACA34 is predicted to guide the pseudouridylation of residue U4269 and U4282 of 28S rRNA . In humans all three of these snoRNAs share the same host gene .
