What is the function of this protein?
Required for proper microtubule dynamics.  Plays a role in the cytoskeletal changes that accompany neuronal differentiation and neurite extension (By similarity).  Possibly MAP1B binds to at least two tubulin subunits in the polymer, and this bridging of subunits might be involved in nucleating microtubule polymerization and in stabilizing microtubules.  Acts as a positive cofactor in DAPK1-mediated autophagic vesicle formation and membrane blebbing (By similarity).  Facilitates tyrosination of alpha-tubulin in neuronal microtubules.  Required for synaptic maturation (By similarity).
What are the official names of this protein?
Microtubule-associated protein 1B, MAP-1B, Neuraxin.
What is the protein family that this protein belongs to?
Belongs to the MAP1 family.
What are the subcellular locations of this protein?
Cytoplasm, cytoskeleton. Cytoplasm. Synapse. Cell projection, dendritic spine. Note=Colocalizes with DAPK1 in the microtubules and cortical actin fibers. SUBCELLULAR LOCATION: [MAP1 light chain LC1]: Cytoplasm.
