MAP1B (microtubule-associated protein 1B) is the major cytoskeletal constituent of developing nervous system wherein it plays a key role in neuronal migration as well as differentiation. MAP1B interacts with LC1, ANP32A, TIAM2, GAN, DAPK1, tubulin tyrosine TTL etc. and binds at least two tubulin subunits in the polymer which is critical in nucleating microtubule polymerization as well as in stabilizing the microtubules. MAP1B is one of the major phosphorylation substrates for GSK-3beta which phosphorylates it at Ser1260/Thr1265 in differentiating neurons, a molecular switch for MAP1B mediated regulation of microtubule dynamics in the growing axons and the growth cones. MAP1B acts as a positive cofactor in DAPK1-mediated autophagic vesicle formation/membrane blebbing and also brings about tyrosination of alpha-tubulin in neuronal microtubules along with its essential role in synaptic maturation. MAP1B is downstream of various signalling pathways that stimulate neurite growth or direct growth cone pathfinding, e.g. laminin, netrins, neurotrophins, wingless/integration site, or that influence neuronal migration, e.g. reelin. MAP1B is implicated in a number of neurological disorders, such as fragile X syndrome and giant axonal neuropathy.
