Protein existence	Evidence at protein level

General annotation (Comments)

Function	Participates in pre-mRNA splicing. Part of the U4/U5/U6 tri-snRNP complex, one of the building blocks of the spliceosome.
Subunit structure	Interacts directly with PRPF4. Part of a heteromeric complex containing PPIH, PRPF3 and PRPF4 that is stable in the absence of RNA. 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. Ref.1 Ref.2 Ref.7
Subcellular location	Nucleus speckle. Note: Colocalizes with spliceosomal snRNPs.
Tissue specificity	Highly expressed in retina, liver, kidney and blood. Detected at lower levels in heart and brain. Ref.15
Involvement in disease	Retinitis pigmentosa 18 (RP18) [MIM:601414]: A 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. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.15 Ref.16 Ref.17
Sequence similarities	Contains 1 PWI domain.
