Calcium 10-17 immunoglobulin lambda variable 2-18 Homo sapiens 119-127 21167176-1 2011 The function of the human voltage-gated sodium channel Na(V)1.5 is regulated in part by intracellular calcium signals. Calcium 102-109 immunoglobulin lambda variable 2-18 Homo sapiens 55-63 21167176-2 2011 The ubiquitous calcium sensor protein calmodulin (CaM) is an important part of the complex calcium-sensing apparatus in Na(V)1.5. Calcium 15-22 immunoglobulin lambda variable 2-18 Homo sapiens 120-128 21167176-7 2011 Sequence similarities between voltage-gated sodium channels and voltage-gated calcium channels suggest that the structure of the CaM-Na(V)1.5 IQ motif complex can serve as a general model for the interaction between CaM and ion channel IQ motifs under low-calcium conditions.
