Promotes neuronal apoptosis by up-regulating cyclin-D1 (CCND1) expression. This is done by the phosphorylation of SRSF2, leading to the suppression of p53/TP53 phosphorylation thereby relieving the repressive effect of p53/TP53 on cyclin-D1 (CCND1) expression. Phosphorylates ACIN1, and redistributes it from the nuclear speckles to the nucleoplasm, resulting in cyclin A1 but not cyclin A2 up- regulation. Plays an essential role in spliceosomal B complex formation via the phosphorylation of DDX23/PRP28. Can mediate hepatitis B virus (HBV) core protein phosphorylation. Plays a negative role in the regulation of HBV replication through a mechanism not involving the phosphorylation of the core protein but by reducing the packaging efficiency of the pregenomic RNA (pgRNA) without affecting the formation of the viral core particles. {ECO:0000269|PubMed:12134018, ECO:0000269|PubMed:16122776, ECO:0000269|PubMed:18425142, ECO:0000269|PubMed:18559500, ECO:0000269|PubMed:19592491, ECO:0000269|PubMed:21056976, ECO:0000269|PubMed:21157427, ECO:0000269|PubMed:9472028}. |Pkinase| |Pkinase Tyr| |nuclear speck organization| |nuclear body organization| |14-3-3 protein binding| |positive regulation of viral genome replication| |positive regulation of neuron apoptotic process| |spliceosomal complex assembly| |negative regulation of viral genome replication| |positive regulation of viral life cycle| |negative regulation of viral life cycle| |positive regulation of neuron death| |regulation of viral genome replication| |negative regulation of viral process| |regulation of mRNA splicing, via spliceosome| |positive regulation of viral process| |nucleus organization| |regulation of RNA splicing| |regulation of mRNA processing| |regulation of viral life cycle| |regulation of viral process| |regulation of neuron apoptotic process| |magnesium ion binding| |negative regulation of multi-organism process| |regulation of symbiosis, encompassing mutualism through parasitism| |ribonucleoprotein complex assembly| |ribonucleoprotein complex subunit organization| |RNA splicing, via transesterification reactions with bulged adenosine as nucleophile| |mRNA splicing, via spliceosome| |RNA splicing, via transesterification reactions| |regulation of neuron death| |angiogenesis| |regulation of mRNA metabolic process| |protein serine/threonine kinase activity| |positive regulation of cell cycle| |RNA splicing| |blood vessel morphogenesis| |ribonucleoprotein complex biogenesis| |mRNA processing| |blood vessel development| |positive regulation of multi-organism process| |vasculature development| |cardiovascular system development| |positive regulation of apoptotic process| |positive regulation of programmed cell death| |tube morphogenesis| |mRNA metabolic process| |positive regulation of cell death| |innate immune response| |regulation of multi-organism process| |cellular protein-containing complex assembly| |tube development| |nucleolus| |circulatory system development| |RNA processing| |anatomical structure formation involved in morphogenesis| |positive regulation of cell population proliferation| |defense response to other organism| |protein phosphorylation| |regulation of cell cycle| |phosphorylation| |response to other organism| |response to external biotic stimulus| |response to biotic stimulus| |defense response| |RNA binding| |ATP binding| |regulation of apoptotic process| |protein-containing complex assembly| |regulation of programmed cell death| |regulation of cell population proliferation| |RNA metabolic process| |regulation of cell death| |intracellular signal transduction| |protein-containing complex subunit organization| |immune response| |positive regulation of gene expression| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp528|TGF-beta1 44ng/ml R08 exp528]]|-1.88| No correlation found to any other genes in chemogenomics.
