Microtubule association of a neuronal RNA-binding protein HuD through its binding to the light chain of MAP1B

► The RNA binding protein HuD binds to the light chain of microtubule associated protein MAP1B (LC1). ► LC1 directly associates with HuD via C-terminal region. ► HuD, even in the RNA-bound form, can form a complex with LC1. ► HuD tightly associates with microtubules through the interaction with LC1.
