======= PRPF4 ======= == Gene Information == * **Official Symbol**: PRPF4 * **Official Name**: pre-mRNA processing factor 4 * **Aliases and Previous Symbols**: N/A * **Entrez ID**: [[https://www.ncbi.nlm.nih.gov/gene/?term=9128|9128]] * **UniProt**: [[https://www.uniprot.org/uniprot/O43172|O43172]] * **Interactions**: [[https://thebiogrid.org/search.php?search=PRPF4&organism=9606|BioGRID]] * **PubMed articles**: [[https://www.ncbi.nlm.nih.gov/pubmed/?term=gene%20PRPF4|Open PubMed]] * **OMIM**: [[https://omim.org/entry/607795|Open OMIM]] == Function Summary == * **Entrez Summary**: The protein encoded by this gene is part of a heteromeric complex that binds U4, U5, and U6 small nuclear RNAs and is involved in pre-mRNA splicing. The encoded protein also is a mitotic checkpoint protein and a regulator of chemoresistance in human ovarian cancer. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2016]. * **UniProt Summary**: Participates in pre-mRNA splicing. Part of the U4/U5/U6 tri-snRNP complex, one of the building blocks of the spliceosome. {ECO:0000269|PubMed:25383878}. |WD40| |PRP4| |spliceosomal snRNP complex| |U4/U6 snRNP| |U4 snRNA binding| |U6 snRNA binding| |U4/U6 x U5 tri-snRNP complex| |U2-type precatalytic spliceosome| |Cajal body| |spliceosomal complex| |mRNA splicing, via spliceosome| |RNA splicing, via transesterification reactions with bulged adenosine as nucleophile| |RNA splicing, via transesterification reactions| |RNA splicing| |nuclear speck| |mRNA processing| |mRNA metabolic process| |RNA processing| |RNA metabolic process| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp349|Cytochalasin-B 5μM R07 exp349]]|-2.15| |[[:results:exp526|Sulforaphane 9μM R08 exp526 no dilution day6]]|-2.11| |[[:results:exp521|Salinomycin 3.5μM R08 exp521]]|-2.06| |[[:results:exp319|ABT-702 5μM plus Dimethyloxaloylglycine 11μM R07 exp319]]|-1.93| |[[:results:exp382|Palbociclib 1μM R07 exp382]]|-1.88| |[[:results:exp448|Ammonium tetrathiomolybdate 10μM R08 exp448]]|-1.81| |[[:results:exp232|Epothilone-D 0.004 to 0.006μM on day4 R05 exp232]]|1.71| |[[:results:exp65|Mubritinib 0.2μM R02 exp65]]|1.73| |[[:results:exp356|Docosahexaenoic-acid 50μM R07 exp356]]|1.75| |[[:results:exp70|INK128 0.2μM R02 exp70]]|1.81| |[[:results:exp151|SGC0946 7μM R03 exp151]]|1.82| |[[:results:exp176|Apcin 50 to 100μM on day4 R04 exp176]]|1.9| |[[:results:exp130|JQ1 0.01μM R03 exp130]]|1.93| |[[:results:exp293|Myriocin 25μM R06 exp293]]|1.98| |[[:results:exp144|PFI-3 10μM R03 exp144]]|2.12| |[[:results:exp83|Trametinib 10μM R02 exp83]]|2.39| |[[:results:exp129|Isonicotinamide 500μM R03 exp129]]|2.43| |[[:results:exp234|Ethanol 0.01 R05 exp234]]|2.44| ^Gene^Correlation^ |[[:human genes:m:madcam1|MADCAM1]]|0.438| |[[:human genes:a:atxn1|ATXN1]]|0.437| |[[:human genes:k:kpnb1|KPNB1]]|0.4| Global Fraction of Cell Lines Where Essential: 408/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|1/1| |909776.0|1/1| |bile duct|15/28| |blood|18/28| |bone|13/26| |breast|16/33| |central nervous system|25/56| |cervix|1/4| |colorectal|11/17| |esophagus|4/13| |fibroblast|0/1| |gastric|10/16| |kidney|10/21| |liver|13/20| |lung|41/75| |lymphocyte|7/16| |ovary|18/26| |pancreas|17/24| |peripheral nervous system|14/16| |plasma cell|6/15| |prostate|1/1| |skin|12/24| |soft tissue|7/9| |thyroid|1/2| |upper aerodigestive|11/22| |urinary tract|15/29| |uterus|5/5| == Essentiality in NALM6 == * **Essentiality Rank**: 578 * **Expression level (log2 read counts)**: 6.43 {{:chemogenomics:nalm6 dist.png?nolink |}}
