MAP1B | definition of MAP1B by Medical dictionary
Also found in: Acronyms
MAP1B A gene on chromosome 5q13 that encodes a protein belonging to the microtubule-associated protein family, which are involved in microtubule assembly, an essential step in neurogenesis. The MAP1B protein product is a precursor polypeptide, which is thought to undergo proteolytic processing to yield a MAP1B heavy chain and LC1 light chain. Mouse knockout studies suggest a role in development and function of the nervous system.

Two known examples are neurofilament light chain (Nefl)  and microtubule-associated protein 1b (Map1b), the latter of which is the homologue of Drosophila Futsch [75, 76].
Recent work from the Shen group provides evidence that TDP-43 and FMRP coregulate dendritic translation of ~160 common targets, including Rac1, GluA1, and Map1b .
GluN3A also interacts with MAP1B  and MAP1-s .
