Protein Information (annotations from UniProt)

Database IDHIV0003740
UniProt IDO60306
Primary gene name(s)AQR
Synonym gene name(s)KIAA0560
Protein nameIntron-binding protein aquarius
Protein functionIntron-binding spliceosomal protein required to link pre-mRNA splicing and snoRNP, small nucleolar ribonucleoprotein biogenesis. Plays a key role in position-dependent assembly of intron-encoded box C/D small snoRNP, splicing being required for snoRNP assembly. May act by helping the folding of the snoRNA sequence. Binds to intron of pre-mRNAs in a sequence-independent manner, contacting the region between snoRNA and the branchpoint of introns, 40 nucleotides upstream of the branchpoint during the late stages of splicing. {ECO:0000269|PubMed:16949364}.
Subcellular locationNucleus {ECO:0000269|PubMed:16949364}. Note=Localizes to speckle-like regions of the nucleoplasm. {ECO:0000269|PubMed:16949364}.
