Gene name:
MAPK8IP1 (IB1;JIP1;PRKM8IP) ;
Protein name:
C-Jun-amino-terminal kinase-interacting protein 1 (JIP-1;JNK-interacting protein 1) ;
Alternative:
JNK MAP kinase scaffold protein 1 ;Islet-brain 1 (IB-1) ;Mitogen-activated protein kinase 8-interacting protein 1 ;
Organism:
Human (Homo sapiens).
General Annotation
Sub Unit:
Forms homo- or heterooligomeric complexes. Binds specific components of the JNK signaling pathway namely, MAPK8, MAPK9, MAPK10, MAPKK7, MLK2, MLK3, MAP3K12 and MAP3K13. Also binds the proline-rich domain-containing splice variant of apolipoprotein E receptor 2 (ApoER2). Interacts, via the PID domain, with RGNEF. Binds the cytoplasmic tails of LRP1 and LRP2 (Megalin). Binds the TPR motif-containing C-terminal of KNS2, then the pre-assembled MAPK8IP1 scaffolding complexes are transported as a cargo of kinesin, to the required subcellular location. Interacts with the cytoplasmic domain of APP (By similarity). Interacts with MAP3K7. Interacts with isoform 1 and isoform 2 of VRK2.
Function:
The JNK-interacting protein (JIP) group of scaffold proteins selectively mediates JNK signaling by aggregating specific components of the MAPK cascade to form a functional JNK signaling module. 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.
Subcellular Location:
Cytoplasm
Cytoplasm
perinuclear region
Nucleus
Endoplasmic reticulum membrane
Mitochondrion membrane
Accumulates in cell surface projections. Under certain stress conditions, translocates to the perinuclear region of neurons. In insulin-secreting cells, detected in both the cytoplasm and nucleus.
