ID:TAOK3_HUMAN DESCRIPTION: RecName: Full=Serine/threonine-protein kinase TAO3; EC=2.7.11.1; AltName: Full=Cutaneous T-cell lymphoma-associated antigen HD-CL-09; Short=CTCL-associated antigen HD-CL-09; AltName: Full=Dendritic cell-derived protein kinase; AltName: Full=JNK/SAPK-inhibitory kinase; AltName: Full=Jun kinase-inhibitory kinase; AltName: Full=Kinase from chicken homolog A; Short=hKFC-A; AltName: Full=Thousand and one amino acid protein 3; FUNCTION: Serine/threonine-protein kinase that acts as a regulator of the p38/MAPK14 stress-activated MAPK cascade and of the MAPK8/JNK cascade. Acts as an activator of the p38/MAPK14 stress- activated MAPK cascade. In response to DNA damage, involved in the G2/M transition DNA damage checkpoint by activating the p38/MAPK14 stress-activated MAPK cascade, probably by mediating phosphorylation of upstream MAP2K3 and MAP2K6 kinases. Inhibits basal activity of MAPK8/JNK cascade and diminishes its activation in response epidermal growth factor (EGF). CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. SUBUNIT: Self-associates. Interacts with ERN1 and TRAF2. Interaction with TRAF2 is facilitated under ER stress conditions, such as treatment with tunicamycin, and may promote TRAF2 phosphorylation. INTERACTION: O75460:ERN1; NbExp=3; IntAct=EBI-1384100, EBI-371750; Q12933:TRAF2; NbExp=2; IntAct=EBI-1384100, EBI-355744; SUBCELLULAR LOCATION: Cytoplasm. Cell membrane; Peripheral membrane protein. Note=Also localized to the peripheral cell membrane. TISSUE SPECIFICITY: Ubiquitously expressed at a low level, and highly expressed in peripheral blood leukocytes (PBLs), thymus, spleen, kidney, skeletal muscle, heart and liver. PTM: Autophosphorylated. Phosphorylated upon DNA damage, probably by ATM or ATR. Phosphorylation at Ser-324 by ATM following DNA damage is required for activation of the p38/MAPK14 stress- activated MAPK cascade. Phosphorylated by LRRK2. SIMILARITY: Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. STE20 subfamily. SIMILARITY: Contains 1 protein kinase domain. SEQUENCE CAUTION: Sequence=AAN09723.1; Type=Erroneous initiation; Note=Translation N-terminally extended;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
