Chain A (DUS19_HUMAN | Q8WTR2)

molecular function
	GO:0008579	JUN kinase phosphatase activity	Catalysis of the reaction: JUN kinase serine/threonine/tyrosine phosphate + H2O = JUN kinase serine/threonine/tyrosine + phosphate.
	GO:0005078	MAP-kinase scaffold activity	The binding activity of a molecule that functions as a physical support for the assembly of a multiprotein mitogen-activated protein kinase (MAPK) complex. Binds multiple kinases of the MAPKKK cascade, and also upstream signaling proteins, permitting those molecules to function in a coordinated way. Bringing together multiple enzymes and their substrates enables the signal to be transduced quickly and efficiently.
	GO:0016787	hydrolase activity	Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
	GO:0031435	mitogen-activated protein kinase kinase kinase binding	Interacting selectively and non-covalently with a mitogen-activated protein kinase kinase kinase, any protein that can phosphorylate a MAP kinase kinase.
	GO:0016791	phosphatase activity	Catalysis of the hydrolysis of phosphoric monoesters, releasing inorganic phosphate.
	GO:0004721	phosphoprotein phosphatase activity	Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate. Together with protein kinases, these enzymes control the state of phosphorylation of cell proteins and thereby provide an important mechanism for regulating cellular activity.
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
	GO:0030295	protein kinase activator activity	Binds to and increases the activity of a protein kinase, an enzyme which phosphorylates a protein.
	GO:0004860	protein kinase inhibitor activity	Stops, prevents or reduces the activity of a protein kinase, an enzyme which phosphorylates a protein.
	GO:0004725	protein tyrosine phosphatase activity	Catalysis of the reaction: protein tyrosine phosphate + H2O = protein tyrosine + phosphate.
	GO:0008138	protein tyrosine/serine/threonine phosphatase activity	Catalysis of the reactions: protein serine + H2O = protein serine + phosphate; protein threonine phosphate + H2O = protein threonine + phosphate; and protein tyrosine phosphate + H2O = protein tyrosine + phosphate.
biological process
	GO:0032147	activation of protein kinase activity	Any process that initiates the activity of an inactive protein kinase.
	GO:0016311	dephosphorylation	The process of removing one or more phosphoric (ester or anhydride) residues from a molecule.
	GO:0046329	negative regulation of JNK cascade	Any process that stops, prevents, or reduces the frequency, rate or extent of signal transduction mediated by the JNK cascade.
	GO:0043508	negative regulation of JUN kinase activity	Any process that stops, prevents, or reduces the frequency, rate or extent of JUN kinase activity.
	GO:0006469	negative regulation of protein kinase activity	Any process that stops, prevents, or reduces the frequency, rate or extent of protein kinase activity.
	GO:0035335	peptidyl-tyrosine dephosphorylation	The removal of phosphoric residues from peptidyl-O-phospho-tyrosine to form peptidyl-tyrosine.
	GO:0046330	positive regulation of JNK cascade	Any process that activates or increases the frequency, rate or extent of signal transduction mediated by the JNK cascade.
	GO:0043507	positive regulation of JUN kinase activity	Any process that activates or increases the frequency, rate or extent of JUN kinase activity.
	GO:0043410	positive regulation of MAPK cascade	Any process that activates or increases the frequency, rate or extent of signal transduction mediated by the MAPK cascade.
	GO:0045860	positive regulation of protein kinase activity	Any process that activates or increases the frequency, rate or extent of protein kinase activity.
	GO:0006470	protein dephosphorylation	The process of removing one or more phosphoric residues from a protein.
