| Thus, the 14–3-3 protein interactions with PLN serve to stabilize the phosphoform and disinhibit its effect on SERCA activity. | PMID 34820713 | 0.91 |
| Consistent with PLN acting as a dynamic hub in the control of Ca 2+ handling, our results identify 14-3-3 binding to PLN as a contractility-augmenting mechanism. | PMID 32873725 | 0.91 |
| Probably the most compelling examination of 14–3-3 protein function in the context cardiac muscle ECC is the recognition that 14–3-3 proteins interact with Phospholamban (PLN) [ xref ]. | PMID 34820713 | 0.91 |
| Physiologically, the 14–3-3 protein interaction with PLN was promoted following β-adrenergic stimulation and shown to slow the kinetics of PLN dephosphorylation by masking the phosphosite on PLN. | PMID 34820713 | 0.91 |
| However, the discovery that 14–3-3 proteins interact directly with phospholamban to alter reuptake kinetics of Ca 2+ into the sarcoplasmic reticulum within the cardiac myocyte represents the most direct mechanism to date and provides pivotal support to their role in ECC. | PMID 34820713 | 0.88 |
| Apart from PKA and SERCA2a, pentamerization of PLN has been shown to affect the interaction with 14–3–3 proteins that preferentially bind to phosphorylated PLN pentamers, protecting pentamers from dephosphorylation and thereby adding another level of activity modulation. xref Finally, PLN oligomers would enhance distinct phosphorylation states of monomeric and pentameric PLN since pentamer dephosphorylation occurs by a co-operative mechanism. xref | PMID 36869774 | 0.87 |
| In contrast, during β -adrenergic stimulation, 14-3-3’s binding to phosphorylated phospholamban prevents its dephosphorylation, thereby maintaining SERCA in an activated state ( xref ). | PMID 39869803 | 0.86 |
