Overview
Mermaid diagram (expand to render)
TBC1D24 encodes a member of the TBC (Tre2-Bub2-Cdc16) domain family of Rab GTPase-activating proteins (GAPs). The protein contains an N-terminal synaptobrevin-like domain and a C-terminal TBC domain with GAP activity. TBC1D24 is highly expressed in the brain and plays critical roles in synaptic vesicle trafficking, endolysosomal trafficking, and neuronal development. Mutations in TBC1D24 cause various neurological disorders including epilepsy, hearing loss, and have been implicated in ALS and FTD. [@maier2021]
