ID:PRP6_HUMAN DESCRIPTION: RecName: Full=Pre-mRNA-processing factor 6; AltName: Full=Androgen receptor N-terminal domain-transactivating protein 1; Short=ANT-1; AltName: Full=PRP6 homolog; AltName: Full=U5 snRNP-associated 102 kDa protein; Short=U5-102 kDa protein; FUNCTION: Involved in pre-mRNA splicing. May act in the tri-snRNP complex as a bridging factor between U5 and U4/U6 snRNPs in the late step of spliceosome assembly. May be necessary for tri-snRNP formation. Enhances dihydrotestosterone-induced transactivation activity of AR, as well as dexamethasone-induced transactivation activity of NR3C1, but does not affect estrogen-induced transactivation. SUBUNIT: Associates with the U5 snRNP particle (containing the 40 kDa, 52 kDa, 116 kDa, 200 kDa and 220 kDa proteins) probably via interaction(s) with the 220 kDa and/or other proteins. Associates with U4/U6 snRNP particle (containing the 15.5 kDa, 20 kDa/60kDa/90kDa heteromer, LSm proteins LSm2-8, 61 kDa and Sm proteins). Interacts with ARAF1. Identified in the spliceosome C complex. Interacts with AR and NR3C1, but not ESR1, independently of the presence of hormones. INTERACTION: P10398:ARAF; NbExp=4; IntAct=EBI-536755, EBI-365961; SUBCELLULAR LOCATION: Nucleus, nucleoplasm. Nucleus speckle. Note=Localized in splicing speckles. TISSUE SPECIFICITY: Widely expressed. DISEASE: Defects in PRPF6 may be the cause of retinitis pigmentosa type 60 (RP60) [MIM:613983]. 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=Cells from RP60 patients show intron retention for pre-mRNA bearing specific splicing signals. SIMILARITY: Contains 9 HAT repeats.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
