Biochemical assessment of α-α-subunit interactions of Nav1.5 in a heterologous expression system

Oksana Iamshanova, Anne-Flore Hämmerli, Suberja Sundaralingam, Arbresh Seljmani, Sabrina Guichard, Maria C. Essers, Jean‐Sébastien Rougier, Hugues Abriel

This study assesses α-α-subunit interactions of Nav1.5 in a heterologous expression system and finds that interactions depend on N-linked glycosylation and non-native disulfide bonds.
