molecular function
	GO:0019899	enzyme binding	Interacting selectively and non-covalently with any enzyme.
	GO:0046875	ephrin receptor binding	Interacting selectively and non-covalently with an ephrin receptor.
	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:0005158	insulin receptor binding	Interacting selectively and non-covalently with the insulin receptor.
	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:0019901	protein kinase binding	Interacting selectively and non-covalently with a protein kinase, any enzyme that catalyzes the transfer of a phosphate group, usually from ATP, to a protein substrate.
	GO:0051721	protein phosphatase 2A binding	Interacting selectively and non-covalently with the enzyme protein phosphatase 2A.
	GO:0004725	protein tyrosine phosphatase activity	Catalysis of the reaction: protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

biological process
	GO:0036498	IRE1-mediated unfolded protein response	A series of molecular signals mediated by the endoplasmic reticulum stress sensor IRE1 (Inositol-requiring transmembrane kinase/endonuclease). Begins with activation of IRE1 in response to endoplasmic reticulum (ER) stress, and ends with regulation of a downstream cellular process, e.g. transcription. One target of activated IRE1 is the transcription factor HAC1 in yeast, or XBP1 in mammals; IRE1 cleaves an intron of a mRNA coding for HAC1/XBP1 to generate an activated HAC1/XBP1 transcription factor, which controls the up regulation of UPR-related genes. At least in mammals, IRE1 can also signal through additional intracellular pathways including JNK and NF-kappaB.
	GO:0060397	JAK-STAT cascade involved in growth hormone signaling pathway	The process in which STAT proteins (Signal Transducers and Activators of Transcription) are activated by members of the JAK (janus activated kinase) family of tyrosine kinases, following the binding of physiological ligands to the growth hormone receptor. Once activated, STATs dimerize and translocate to the nucleus and modulate the expression of target genes.
	GO:0031532	actin cytoskeleton reorganization	A process that is carried out at the cellular level which results in dynamic structural changes to the arrangement of constituent parts of cytoskeletal structures comprising actin filaments and their associated proteins.
	GO:0007257	activation of JUN kinase activity	The initiation of the activity of the inactive enzyme JUN kinase (JNK).
	GO:0006987	activation of signaling protein activity involved in unfolded protein response	The conversion of a specific protein, possessing protein kinase and endoribonuclease activities, to an active form as a result of signaling via the unfolded protein response.
	GO:0016311	dephosphorylation	The process of removing one or more phosphoric (ester or anhydride) residues from a molecule.
	GO:0030968	endoplasmic reticulum unfolded protein response	The series of molecular signals generated as a consequence of the presence of unfolded proteins in the endoplasmic reticulum (ER) or other ER-related stress; results in changes in the regulation of transcription and translation.
	GO:0008286	insulin receptor signaling pathway	The series of molecular signals generated as a consequence of the insulin receptor binding to insulin.
	GO:0070373	negative regulation of ERK1 and ERK2 cascade	Any process that stops, prevents, or reduces the frequency, rate or extent of signal transduction mediated by the ERK1 and ERK2 cascade.
	GO:0043407	negative regulation of MAP kinase activity	Any process that stops, prevents, or reduces the frequency, rate or extent of MAP kinase activity.
	GO:1903898	negative regulation of PERK-mediated unfolded protein response	Any process that stops, prevents or reduces the frequency, rate or extent of the PERK-mediated unfolded protein response.
	GO:1902236	negative regulation of endoplasmic reticulum stress-induced intrinsic apoptotic signaling pathway	Any process that stops, prevents or reduces the frequency, rate or extent of an endoplasmic reticulum stress-induced intrinsic apoptotic signaling pathway.
	GO:0046627	negative regulation of insulin receptor signaling pathway	Any process that stops, prevents, or reduces the frequency, rate or extent of insulin receptor signaling.
	GO:0009968	negative regulation of signal transduction	Any process that stops, prevents, or reduces the frequency, rate or extent of signal transduction.
	GO:0030948	negative regulation of vascular endothelial growth factor receptor signaling pathway	Any process that stops, prevents, or reduces the frequency, rate or extent of vascular endothelial growth factor receptor signaling pathway activity.

	GO:1990264	peptidyl-tyrosine dephosphorylation involved in inactivation of protein kinase activity	Any peptidyl-tyrosine dephosphorylation that is involved in inactivation of protein kinase activity.
	GO:0035791	platelet-derived growth factor receptor-beta signaling pathway	A series of molecular signals initiated by the binding of a ligand to a beta-type platelet-derived growth factor receptor (PDGFbeta) on the surface of a signal-receiving cell, and ending with regulation of a downstream cellular process, e.g. transcription.
	GO:1903896	positive regulation of IRE1-mediated unfolded protein response	Any process that activates or increases the frequency, rate or extent of the IRE1-mediated unfolded protein response.
	GO:0061098	positive regulation of protein tyrosine kinase activity	Any process that increases the rate, frequency, or extent of protein tyrosine kinase activity.
	GO:2000646	positive regulation of receptor catabolic process	Any process that activates or increases the frequency, rate or extent of receptor catabolic process.
	GO:0006470	protein dephosphorylation	The process of removing one or more phosphoric residues from a protein.
	GO:0030100	regulation of endocytosis	Any process that modulates the frequency, rate or extent of endocytosis.

	GO:0060338	regulation of type I interferon-mediated signaling pathway	Any process that modulates the rate, frequency or extent of a type I interferon-mediated signaling pathway. A type I interferon-mediated signaling pathway is the series of molecular events generated as a consequence of a type I interferon binding to a cell surface receptor.
	GO:0034976	response to endoplasmic reticulum stress	Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stress acting at the endoplasmic reticulum. ER stress usually results from the accumulation of unfolded or misfolded proteins in the ER lumen.
cellular component
