What is the function of this protein?
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 (PubMed:12189133).  May function as a regulator of vesicle transport, through interactions with the JNK-signaling components and motor proteins (By similarity).  Promotes neuronal axon elongation in a kinesin- and JNK-dependent manner.  Activates cofilin at axon tips via local activation of JNK, thereby regulating filopodial dynamics and enhancing axon elongation.  Its binding to kinesin heavy chains (KHC), promotes kinesin-1 motility along microtubules and is essential for axon elongation and regeneration.  Regulates cortical neuronal migration by mediating NTRK2/TRKB anterograde axonal transport during brain development (By similarity).  Acts as an adapter that bridges the interaction between NTRK2/TRKB and KLC1 and drives NTRK2/TRKB axonal but not dendritic anterograde transport, which is essential for subsequent BDNF-triggered signaling and filopodia formation (PubMed:21775604).
What are the official names of this protein?
C-Jun-amino-terminal kinase-interacting protein 3, JIP-3, JNK-interacting protein 3, JNK MAP kinase scaffold protein 3, Mitogen-activated protein kinase 8-interacting protein 3.
What is the protein family that this protein belongs to?
Belongs to the JIP scaffold family.
What are the subcellular locations of this protein?
Cytoplasm. Golgi apparatus. Cytoplasmic vesicle. Cell projection, growth cone. Cell projection, axon. Cell projection, dendrite. Cytoplasm, perinuclear region. Note=Localized in the soma and growth cones of differentiated neurites and the Golgi and vesicles of the early secretory compartment of epithelial cells. KIF5A/B/C-mediated transportation to axon tips is essential for its function in enhancing neuronal axon elongation.
