. "SEQUENCE 547 AA; 60724 MW; D8B7D9955B06862F CRC64;"^^ . "FUNCTION: Constitutively active kinase which may function as a negative regulator of cell growth. In vitro, phosphorylates FOS. CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. ENZYME REGULATION: Activated by threonine and tyrosine phosphorylation. Inhibited by dual specificity phosphatases, such as DUSP1. SUBUNIT: Interacts with TGFB1I1. SUBCELLULAR LOCATION: Nucleus. TISSUE SPECIFICITY: Ubiquitously expressed at a weak level. Highest expression is found in testis and to a lower extent in lung. DOMAIN: C-terminal domain, rather than the kinase activity, is required for the full function of the enzyme. This region may be a protein interaction domain that regulates kinase localization, activation and transcriptional activity. When C-terminally truncated, the enzyme shows a reduction in the Thr-Glu-Tyr (TEY) phosphorylation level, in the in vitro kinase activity, in its nuclear localization and in its inhibitory effect on cell growth. DOMAIN: The N-terminal region (1-20) is the minimal region necessary for ubiquitination and further proteasomal degradation. DOMAIN: The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases. PTM: Dually phosphorylated on Thr-176 and Tyr-178, which activates the enzyme. Autophosphorylated on threonine and tyrosine residues. PTM: Ubiquitinated. Ubiquitination may allow its tight kinase activity regulation and rapid turnover. May be ubiquitinated by a SCF E3 ligase. SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily. SIMILARITY: Contains 1 protein kinase domain. GENE SYNONYMS:Mapk15 Erk7.
