Phosphorylates the microtubule-associated protein MAPT (PubMed:14594945, PubMed:23666762). Also phosphorylates the microtubule-associated proteins MAP2 and MAP4 (PubMed:14594945). Involved in regulation of the microtubule network, causing reorganization of microtubules into bundles (PubMed:14594945, PubMed:25123532). Required for the initiation of axoneme extension during cilium assembly (PubMed:23400999). Regulates the centrosomal location of ODF2 and phosphorylates ODF2 in vitro (PubMed:23400999). Plays a role in cell cycle progression, specifically in the G1/S checkpoint (PubMed:25123532). Reduces neuronal cell survival (PubMed:15009667). Plays a role in energy homeostasis by regulating satiety and metabolic rate (By similarity). Promotes adipogenesis by activating JNK1 and inhibiting the p38MAPK pathway, and triggers apoptosis by activating the JNK1 pathway (By similarity). Phosphorylates mTORC1 complex member RPTOR and acts as a negative regulator of the mTORC1 complex, probably due to disruption of the interaction between phosphorylated RPTOR and the RRAGA/RRAGC heterodimer which is required for mTORC1 activation (PubMed:23184942). {ECO:0000250|UniProtKB:Q8CIP4, ECO:0000269|PubMed:14594945, ECO:0000269|PubMed:15009667, ECO:0000269|PubMed:23184942, ECO:0000269|PubMed:23400999, ECO:0000269|PubMed:23666762, ECO:0000269|PubMed:25123532}. |Pkinase Tyr| |Pkinase| |KA1| |positive regulation of protein localization to centrosome| |regulation of protein localization to centrosome| |gamma-tubulin complex| |tau-protein kinase activity| |positive regulation of cilium assembly| |gamma-tubulin binding| |tau protein binding| |regulation of centrosome cycle| |positive regulation of organelle assembly| |ubiquitin binding| |regulation of cilium assembly| |microtubule bundle formation| |ciliary basal body-plasma membrane docking| |positive regulation of plasma membrane bounded cell projection assembly| |ciliary basal body| |microtubule cytoskeleton| |midbody| |microtubule organizing center| |organelle localization by membrane tethering| |membrane docking| |regulation of microtubule cytoskeleton organization| |regulation of plasma membrane bounded cell projection assembly| |regulation of cell projection assembly| |regulation of organelle assembly| |regulation of microtubule-based process| |microtubule binding| |neuron projection| |positive regulation of cellular protein localization| |cilium assembly| |protein serine/threonine kinase activity| |cilium organization| |positive regulation of cell projection organization| |dendrite| |plasma membrane bounded cell projection assembly| |cell projection assembly| |microtubule cytoskeleton organization| |centrosome| |cell division| |positive regulation of cellular component biogenesis| |regulation of cellular protein localization| |regulation of cytoskeleton organization| |organelle localization| |positive regulation of organelle organization| |positive regulation of programmed cell death| |microtubule-based process| |regulation of plasma membrane bounded cell projection organization| |positive regulation of cell death| |regulation of cell projection organization| |regulation of cell cycle process| |organelle assembly| |regulation of cellular localization| |regulation of cellular component biogenesis| |protein phosphorylation| |regulation of protein localization| |cytoskeleton organization| |plasma membrane bounded cell projection organization| |cell projection organization| |regulation of cell cycle| |positive regulation of cellular component organization| |phosphorylation| |regulation of organelle organization| |cell cycle| |ATP binding| |regulation of programmed cell death| |regulation of cell death| |intracellular signal transduction| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp61|YM155 0.0002μM R01 exp61]]|1.81| |[[:results:exp54|Taxol 0.002μM R01 exp54]]|2.22| No correlation found to any other genes in chemogenomics.
