“…Furthermore, RNA-Seq data from isolated cardiac Purkinje cells and working ventricular myocardium reported Mybphl expression as enriched in Purkinje cells (53.23 ± 26 FPKM in Purkinje cells vs 6.43 ± 3.37 FPKM in ventricular cells) 47 . This data, along with the observation of ventricular arrhythmias in Mybphl null mice and ventricular Mybphl -driven LacZ puncta, support the hypothesis that Mybphl is expressed in specific and critical locations in the ventricular conduction system.…”

“…The Fishman lab has gone on to use CNTN-2 as a powerful tool to help identify other potentially critical proteins that are in Purkinje cells(PCs) and not in ventricular cells (eg. 14,15 ).…”

“…Kim et al [59] found that PCP-4 binds calmodulin, resulting in a 50-fold increase in calcium binding rate. The presence of calmodulin binding with calcium activates CaMKII.…”

“…Downregulation of PCP-4 in disease models: phenylephrine infusion and transverse aortic constriction, showed a proarrhythmogenic cascade, increasing pCaMKII expression and intracellular calcium. Therefore PCP-4 inhibits CaMKII activity and downregulation of PCP-4 relieves this inhibition resulting in increased intracellular calcium and pro-arrhythmic behavior [59].…”
