α/β-Hydrolase domain-containing 6 (ABHD6) accelerates the desensitization and deactivation of TARP γ-2-containing AMPA receptors.

ABHD6 accelerates deactivation and desensitization of TARP γ-2-containing AMPA receptors, influencing synaptic response timing in the mammalian brain.
- Why it matters: Understanding how AMPAR kinetics are regulated is crucial for insights into synaptic transmission and plasticity, yet the role of auxiliary proteins like ABHD6 remains unclear.
- What they did: The study examined the effects of ABHD6 on AMPARs with and without TARP γ-2, using electrophysiological recordings and knockout neurons to assess receptor gating kinetics across various isoforms.
- The result: ABHD6 enhances deactivation and desensitization of TARP γ-2-containing AMPARs, and its absence slows these processes, indicating ABHD6's key role in modulating receptor function in a TARP-dependent manner.
