Structure of the ALS Mutation Target Annexin A11 Reveals a Stabilising N-Terminal Segment.

The functions of the annexin family of proteins involve binding to Ca, lipid membranes, other proteins, and RNA, and the annexins share a common folded core structure at the C terminus. Annexin A11 (AnxA11) has a long N-terminal region, which is predicted to be disordered, binds RNA, and forms membraneless organelles involved in neuronal transport. Mutations in AnxA11 have been linked to amyotrophic lateral sclerosis (ALS).
