Molecular partners of trafficking and localization of NaV1.5 and Kir2.1 in the cardiac myocyte

Molecular partners of trafficking and localization of NaV1.5 and Kir2.1 in the cardiac myocyte. 1, transcription; 2, translation; 3, Golgi-mediated glycosylation; 4, vesicular trafficking; 5, compartmental localization and function; 6, retrograde vesicular trafficking, protein degradation, and recycling. Evidence supports interaction at the membrane through SAP97, syntrophin and AP1.2
