Annotated paper: | Dodson PD, et al. "Presynaptic rat Kv1.2 channels suppress synaptic terminal hyperexcitability following action potential invasion" J Physiol. 2003 Jul 1;550(Pt 1):27-33 PMID:12777451 |

Annotation description: | Voltage clamp experiments in the Calyx of Held using the specific blocker for Kv1.2 TsTX-Kalpha. Note that in this study the Kv1.2 channels are presynaptically very close to but not in the Calyx terminal. rule: NAS_MFCC-BP rationale: Protein has voltage-gated ion channel activity and is localized in teh presynaptic membrane (show with high-resolution technique). The inference to term 'voltage-gated ion channel activity involved in regulation of presynaptic membrane potential (GO:0099508)' is trivial and non-controversial.
