Overview

Munc13-1 (UNC13A) is a protein involved in cellular signaling and molecular processes. It is expressed in various tissues including the brain and plays roles in neuronal function and disease mechanisms.

Structure

Munc13-1 has multiple domains including C1, C2, and MUN domains.

Normal Function

Munc13-1 is a large presynaptic protein that primes synaptic vesicles for release. It is essential for synaptic vesicle priming and determines the size of the readily releasable pool.

Role in Disease

UNC13A variants are associated with ALS and alter synaptic transmission.
