Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Functions as a scaffold that mediates the ordered assembly of spliceosomal proteins and snRNAs. Required for the assembly of the U4/U6-U5 tri-snRNP complex. Functions as scaffold that positions spliceosomal U2, U5 and U6 snRNAs at splice sites on pre-mRNA substrates, so that splicing can occur. Interacts with both the 5' and the 3' splice site.1 Publication1 Publication

Involvement in diseasei

Retinitis pigmentosa 13 (RP13)4 Publications

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well.

Subunit structurei

Part of the U5 snRNP complex. Component of the U4/U6-U5 tri-snRNP complex composed of the U4, U6 and U5 snRNAs and at least PRPF3, PRPF4, PRPF6, PRPF8, PRPF31, SNRNP200, TXNL4A, SNRNP40, DDX23, CD2BP2, PPIH, NHP2L1, EFTUD2, SART1 and USP39. Component of the U5.U4atac/U6atac snRNP complexes in U12-dependent spliceosomes. Found in a mRNA splicing-dependent exon junction complex (EJC) with SRRM1. Interacts with U5 snRNP proteins SNRP116 and SNRNP40. Interacts with EFTUD2 and SNRNP200. Interacts (via the MPN (JAB/Mov34) domain) with PRPF3 ('Lys-63'-linked polyubiquitinated); may stabilize the U4/U6-U5 tri-snRNP complex.17 Publications

Domaini

The MPN (JAB/Mov34) domain has structural similarity with deubiquitinating enzymes, but lacks the residues that would bind the catalytic metal ion.By similarity
Contains a region with structural similarity to reverse transcripase, presenting the classical thumb, fingers and palm architecture, but lacks enzyme activity, since the essential metal-binding residues are not conserved.By similarity
Contains a region with structural similarity to type-2 restriction endonucleases, but the residues that would bind catalytic metal ions in endonucleases are instead involved in hydrogen bonds that stabilize the protein structure.By similarity
Contains a region with structural similarity to RNase H, but lacks RNase H activity.By similarity
