May antagonize in a tissue-specific manner the ability of NOVA1 to activate exon selection. In addition to its function in pre-mRNA splicing, plays also a role in the regulation of translation. Isoform 5 has a reduced affinity for RNA. {ECO:0000269|PubMed:11003644, ECO:0000269|PubMed:12667457}. |RRM 1| |negative regulation of RNA splicing| |mRNA splice site selection| |spliceosomal complex assembly| |regulation of neural precursor cell proliferation| |spliceosomal complex| |cerebellum development| |spinal cord development| |metencephalon development| |growth cone| |regulation of RNA splicing| |hindbrain development| |mRNA binding| |ribonucleoprotein complex assembly| |ribonucleoprotein complex subunit organization| |mRNA splicing, via spliceosome| |RNA splicing, via transesterification reactions with bulged adenosine as nucleophile| |RNA splicing, via transesterification reactions| |neuronal cell body| |RNA splicing| |ribonucleoprotein complex biogenesis| |mRNA processing| |mRNA metabolic process| |brain development| |head development| |cellular protein-containing complex assembly| |RNA processing| |central nervous system development| |negative regulation of RNA metabolic process| |RNA binding| |negative regulation of nucleobase-containing compound metabolic process| |protein-containing complex assembly| |regulation of cell population proliferation| |RNA metabolic process| |negative regulation of gene expression| |protein-containing complex subunit organization| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp380|NMS-873 0.07μM R07 exp380]]|-1.9| |[[:results:exp422|Wiskostatin 3μM R07 exp422]]|-1.87| |[[:results:exp36|TRAIL 50ng/ml R00 exp36]]|1.8| |[[:results:exp215|Colchicine 0.009μM R05 exp215]]|2| No correlation found to any other genes in chemogenomics.
