It is highly similar to JIP-1, a mouse protein known to be a regulator of c-Jun amino-terminal kinase (Mapk8). This protein has been shown to prevent MAPK8 mediated activation of transcription factors, and to decrease IL-1 beta and MAP kinase kinase 1 (MEKK1) induced apoptosis in pancreatic beta cells. This protein also functions as a DNA-binding transactivator of the glucose transporter GLUT2. RE1-silencing transcription factor (REST) is reported to repress the expression of this gene in insulin-secreting beta cells. This gene is found to be mutated in a type 2 diabetes family, and thus is thought to be a susceptibility gene for type 2 diabetes.

Required for JNK activation in response to excitotoxic stress. Cytoplasmic MAPK8IP1 causes inhibition of JNK- regulated activity by retaining JNK in the cytoplasm and inhibiting JNK phosphorylation of c-Jun. May also participate in ApoER2-specific reelin signaling. Directly, or indirectly, regulates GLUT2 gene expression and beta-cell function. Appears to have a role in cell signaling in mature and developing nerve terminals. May function as a regulator of vesicle transport, through interactions with the JNK-signaling components and motor proteins (By similarity). Functions as an anti-apoptotic protein and whose level seems to influence the beta-cell death or survival response. {ECO:0000250}. |PID| |SH3 1| |dentate gyrus mossy fiber| |JUN phosphorylation| |regulation of CD8-positive, alpha-beta T cell proliferation| |JUN kinase binding| |MAP-kinase scaffold activity| |dendritic growth cone| |mitogen-activated protein kinase kinase binding| |negative regulation of JUN kinase activity| |regulation of CD8-positive, alpha-beta T cell activation| |mitogen-activated protein kinase kinase kinase binding| |axonal growth cone| |protein kinase inhibitor activity| |regulation of alpha-beta T cell proliferation| |negative regulation of JNK cascade| |kinesin binding| |negative regulation of stress-activated MAPK cascade| |negative regulation of stress-activated protein kinase signaling cascade| |cell body| |negative regulation of MAP kinase activity| |JNK cascade| |regulation of JUN kinase activity| |regulation of alpha-beta T cell activation| |negative regulation of intrinsic apoptotic signaling pathway| |mitochondrial membrane| |stress-activated MAPK cascade| |negative regulation of protein serine/threonine kinase activity| |positive regulation of JNK cascade| |stress-activated protein kinase signaling cascade| |regulation of T cell proliferation| |regulation of intrinsic apoptotic signaling pathway| |negative regulation of MAPK cascade| |positive regulation of stress-activated MAPK cascade| |positive regulation of stress-activated protein kinase signaling cascade| |regulation of JNK cascade| |regulation of lymphocyte proliferation| |regulation of mononuclear cell proliferation| |regulation of leukocyte proliferation| |negative regulation of protein kinase activity| |negative regulation of apoptotic signaling pathway| |regulation of stress-activated MAPK cascade| |regulation of stress-activated protein kinase signaling cascade| |negative regulation of kinase activity| |synapse| |negative regulation of transferase activity| |regulation of T cell activation| |regulation of MAP kinase activity| |MAPK cascade| |signal transduction by protein phosphorylation| |regulation of apoptotic signaling pathway| |negative regulation of protein phosphorylation| |negative regulation of phosphorylation| |negative regulation of intracellular signal transduction| |regulation of lymphocyte activation| |regulation of protein serine/threonine kinase activity| |positive regulation of MAPK cascade| |negative regulation of phosphate metabolic process| |negative regulation of phosphorus metabolic process| |negative regulation of protein modification process| |regulation of leukocyte activation| |regulation of cell activation| |perinuclear region of cytoplasm| |regulation of cellular response to stress| |regulation of MAPK cascade| |negative regulation of catalytic activity| |regulation of protein kinase activity| |regulation of kinase activity| |negative regulation of apoptotic process| |negative regulation of programmed cell death| |endoplasmic reticulum membrane| |protein phosphorylation| |regulation of transferase activity| |negative regulation of cell death| |positive regulation of protein phosphorylation| |positive regulation of intracellular signal transduction| |negative regulation of cellular protein metabolic process| |positive regulation of phosphorylation| |negative regulation of protein metabolic process| |positive regulation of phosphorus metabolic process| |positive regulation of phosphate metabolic process| |negative regulation of molecular function| |positive regulation of protein modification process| |negative regulation of signal transduction| |phosphorylation| |negative regulation of cell communication| |negative regulation of signaling| |regulation of protein phosphorylation| |regulation of response to stress| |regulation of apoptotic process| |regulation of programmed cell death| |regulation of phosphorylation| |positive regulation of cellular protein metabolic process| |regulation of cell population proliferation| |negative regulation of response to stimulus| |regulation of immune system process| |positive regulation of signal transduction| |regulation of cell death| |intracellular signal transduction| |cellular response to stress| |positive regulation of protein metabolic process| |regulation of phosphate metabolic process| |regulation of phosphorus metabolic process| |positive regulation of cell communication| |positive regulation of signaling| |regulation of intracellular signal transduction| |regulation of protein modification process| |vesicle-mediated transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp51|Nifuroxazide 1μM R01 exp51]]|2.42| No correlation found to any other genes in chemogenomics.
