Interacts with other spliceosomal components, via the RS domains, to form a bridge between the 5'- and 3'-splice site binding components, U1 snRNP and U2AF. Can stimulate binding of U1 snRNP to a 5'-splice site-containing pre-mRNA. Binds to purine-rich RNA sequences, either the octamer, 5'-RGAAGAAC-3' (r=A or G) or the decamers, AGGACAGAGC/AGGACGAAGC. Binds preferentially to the 5'- CGAGGCG-3' motif in vitro. Three copies of the octamer constitute a powerful splicing enhancer in vitro, the ASF/SF2 splicing enhancer (ASE) which can specifically activate ASE-dependent splicing. Isoform ASF-2 and isoform ASF-3 act as splicing repressors. May function as export adapter involved in mRNA nuclear export through the TAP/NXF1 pathway. {ECO:0000269|PubMed:8139654}. |RRM 1| |DNA topoisomerase binding| |mRNA 5-splice site recognition| |alternative mRNA splicing, via spliceosome| |exon-exon junction complex| |mRNA splice site selection| |mRNA cis splicing, via spliceosome| |spliceosomal complex assembly| |regulation of alternative mRNA splicing, via spliceosome| |mRNA 3-end processing| |catalytic step 2 spliceosome| |regulation of mRNA splicing, via spliceosome| |mRNA export from nucleus| |mRNA-containing ribonucleoprotein complex export from nucleus| |ribonucleoprotein complex export from nucleus| |ribonucleoprotein complex localization| |RNA export from nucleus| |RNA 3-end processing| |regulation of RNA splicing| |regulation of mRNA processing| |protein export from nucleus| |mRNA transport| |nuclear export| |mRNA binding| |nucleic acid transport| |RNA transport| |establishment of RNA localization| |RNA localization| |ribonucleoprotein complex assembly| |nucleobase-containing compound transport| |ribonucleoprotein complex subunit organization| |protein-containing complex localization| |nucleocytoplasmic transport| |nuclear transport| |RNA splicing, via transesterification reactions with bulged adenosine as nucleophile| |mRNA splicing, via spliceosome| |RNA splicing, via transesterification reactions| |regulation of mRNA metabolic process| |RNA splicing| |nuclear speck| |ribonucleoprotein complex biogenesis| |mRNA processing| |mRNA metabolic process| |cellular protein-containing complex assembly| |RNA processing| |intracellular protein transport| |RNA binding| |protein transport| |intracellular transport| |peptide transport| |protein-containing complex assembly| |amide transport| |cellular protein localization| |cellular macromolecule localization| |establishment of protein localization| |RNA metabolic process| |establishment of localization in cell| |nitrogen compound transport| |protein-containing complex subunit organization| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp459|Bleomycin 5μM R08 exp459]]|-1.71| |[[:results:exp530|Thioridazine 5μM R08 exp530]]|1.75| |[[:results:exp422|Wiskostatin 3μM R07 exp422]]|1.8| |[[:results:exp25|Oligomycin-A 2μM R00 exp25]]|1.81| ^Gene^Correlation^ |[[:human genes:r:rrm1|RRM1]]|0.508| |[[:human genes:c:c14orf93|C14orf93]]|0.443| |[[:human genes:c:cdc73|CDC73]]|0.436| |[[:human genes:p:ppie|PPIE]]|0.422| |[[:human genes:i:iscu|ISCU]]|0.419| |[[:human genes:p:psmb1|PSMB1]]|0.416| |[[:human genes:p:psmb3|PSMB3]]|0.412| |[[:human genes:r:rad21|RAD21]]|0.41| |[[:human genes:n:nup85|NUP85]]|0.405| |[[:human genes:p:psmd1|PSMD1]]|0.405| |[[:human genes:d:dnm2|DNM2]]|0.401| Global Fraction of Cell Lines Where Essential: 534/726 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|1/1| |909776.0|0/1| |bile duct|22/28| |blood|24/28| |bone|17/25| |breast|26/33| |central nervous system|42/56| |cervix|3/4| |colorectal|12/17| |esophagus|9/13| |fibroblast|1/1| |gastric|9/15| |kidney|12/21| |liver|14/20| |lung|49/75| |lymphocyte|13/14| |ovary|18/26| |pancreas|16/24| |peripheral nervous system|10/16| |plasma cell|14/15| |prostate|1/1| |skin|13/24| |soft tissue|5/7| |thyroid|2/2| |upper aerodigestive|18/22| |urinary tract|21/29| |uterus|3/5| == Essentiality in NALM6 == * **Essentiality Rank**: 29 * **Expression level (log2 read counts)**: 9.16 {{:chemogenomics:nalm6 dist.png?nolink |}}
