Abstract

Calcium-dependent inactivation (CDI) of neuronal voltage-gated Ca2+ channels (CaV1.2) is important for synaptic plasticity, which is associated with learning and memory. The Ca2+-dependent binding of calmodulin (CaM) to CaV1.2 is essential for CDI. Here we report NMR assignments for a CaM mutant (D21A/D23A/D25A/E32Q/D57A/D59A/N61A/E68Q, called CaMEF12) that contains two Ca2+ bound at the third and fourth EF-hands (EF3 and EF4) and is bound to the IQ-motif (residues 1644–1665) from CaV1.2 (BMRB accession no. 27692).
