"The immunoprecipitation results indicated an association of HCN4 and Cav3 in the heart and in HEK293 cells."

"Similarly, EMMPRIN silenced cells showed a significant reduction in the binding of caveolin-3 and HCN4, which regulates the I (f) current, suggesting that, rather than a direct interaction, both proteins bind to EMMPRIN."

"We sought to determine whether HCN4 associates with Cav3 in the heart."

"A similar shift has been previously demonstrated in hESC due to a specific HCN4-Caveolin-3 interaction [ xref ], shift that can be reverted by caveolae disruption with Methyl-β-cyclodextrin or by disruption of the caveolin-binding motif of HCN4 [ xref ]."

"Several studies demonstrated that HCN channels localize to caveolae based on the presence of HCN4 in low-density membrane fractions along with Cav-3 as well as the specific interaction of HCN4 with Cav-3 ( xref ; xref ). xref reported that all HCN isoforms have a conserved caveolin-binding domain which impact both channel function and trafficking."

"However, it is still unknown if HCN4 associates with Cav3."

"These results confirm that the HCN4 and Cav3 proteins may be associated with one another."

"A number of laboratories including ours have provided evidence that HCN4 channels are localized to caveolae based on the presence of HCN4 in low density membrane fractions along with Cav-3 as well as the specific interaction of HCN4 with Cav-3 ( xref ; xref ; xref )."

"We hypothesize that Cav3 associates with HCN4 and regulates the function of HCN4 channel."

"We next tested whether caveolin-3 can bind to HCN4 and EMMPRIN and found that the HCN4 and EMMPRIN complex was preserved when we silenced caveolin-3 expression, indicating a direct interaction between these 2 proteins."

"Interestingly, studies have shown that Cav3 is associated with HCN4, and affects its function [ xref ]."

"In addition to inhibition of the I (f) current, ivabradine may induce cardiac protection by inhibiting ECM degradation through preservation of the caveolin-3/LG and EMMPRIN complex and control heart rate by stabilizing the caveolin-3 and HCN4 complex."

"We conclude that HCN4 associates with Cav3 to form a HCN4 macromolecular complex."

"P104L does not disrupt the association between Cav3 and HCN4."
