Plays a critical role in both constitutive and enhancer- dependent splicing by mediating protein-protein interactions and protein-RNA interactions required for accurate 3'-splice site selection. Acts by enhancing the binding of U2AF2 to weak pyrimidine tracts. Also participates in the regulation of alternative pre-mRNA splicing. Activates exon 5 skipping of PTPRC during T-cell activation; an event reversed by GFI1. Binds to RNA at the AG dinucleotide at the 3'-splice site (By similarity). Shows a preference for AGC or AGA (By similarity). {ECO:0000250|UniProtKB:Q8BGJ9}. |zf-CCCH| |U2AF| |pre-mRNA 3-splice site binding| |mRNA 3-end processing| |spliceosomal complex| |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| |protein export from nucleus| |mRNA transport| |nuclear export| |nucleic acid transport| |RNA transport| |establishment of RNA localization| |RNA localization| |nucleobase-containing compound transport| |protein-containing complex localization| |nucleocytoplasmic transport| |nuclear transport| |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| |intracellular protein transport| |protein transport| |intracellular transport| |peptide transport| |amide transport| |cellular protein localization| |cellular macromolecule localization| |establishment of protein localization| |RNA metabolic process| |establishment of localization in cell| |nitrogen compound transport| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp420|Tunicamycin 0.04 to 0.125μM on day4 R07 exp420]]|1.74| |[[:results:exp376|Losmapimod 1μM R07 exp376]]|1.89| No correlation found to any other genes in chemogenomics.
