Alternative:
JNK/SAPK-associated protein 1(JSAP1);JNK MAP kinase scaffold protein 3;Sunday driver 2;Mitogen-activated protein kinase 8-interacting protein 3;
Organism:

General Annotation
Sub Unit:
Forms homo- or heterooligomeric complexes. The central region of MAPK8IP3 interacts with the C-terminal of MAPK8IP2 but not MAPK8IP1. Binds specific components of the JNK signaling pathway namely MAPK8, MAPK9 and MAPK10 to the N-terminal region, MAP2K4 and MAP2K7 to the central region and MAP3K11 to the C-terminal region. Binds the TPR motif-containing C-terminal of kinesin light chain, pre-assembled MAPK8IP1 scaffolding complexes are then transported as a cargo of kinesin, to the required subcellular location. Interacts with ROCK1 and this interaction is enhanced by ultraviolet-B (UVB) radiation.
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. May function as a regulator of vesicle transport, through interations with the JNK-signaling components and motor proteins.
Subcellular Location:
Cytoplasm
Golgi apparatus
Cytoplasmic vesicle
Cell projection
growth cone
Localized in the soma and growth cones of differentiated neurites and the Golgi and vesicles of the early secretory compartment of epithelial cells.
