| We then evaluated the other 2 CaMKII targets, SERCA2 (sarcoplasmic reticulum Ca 2+ -ATPase 2), which transports calcium into the sarcoplasmic reticulum and PLB (phospholamban), an inhibitor of SERCA2, which reversibly inhibits cardiac SERCA2 activity through intramembrane interactions. | PMID 28662005 | 0.91 |
| For a faster reuptake, inhibition of SERCA2 by phospholamban needs to be disinhibited by phosphorylation of phopholamban.With this knowledge in contraction, it is quite natural to assume that various steps in the intracellular mechanism of contraction also play a role in relaxation. | PMID 39965893 | 0.91 |
| For a faster reuptake, inhibition of SERCA2 by phospholamban needs to be disinhibited by phosphorylation of phopholamban. | PMID 39965893 | 0.90 |
| Several studies have demonstrated reduced SR Ca 2+ uptake in HF resulting from SERCA2 downregulation and reduced pump abundance, increased SERCA2 inhibition by PLB, or reduced SERCA2 pump activity unrelated to PLB [1,9,10] . | PMID 16288776 | 0.87 |
| PLB inhibits SERCA2 activity; however, beta-adrenergic stimulation enhances PKA phosphorylation of PLB, which promotes its oligomerization and the derepression of SERCA2 activity. | PMID 22075671 | 0.85 |
| Phospholamban (PLN) inhibits the activity of SERCA2 in a phosphorylation dependent manner. | PMID 24395194 | 0.85 |
| In resting conditions, SERCA2 is inhibited by unphosphorylated PLB, while upon catecholamine stimulation, PLB is phosphorylated by PKA and its inhibitory effect on SERCA2 is released, allowing more efficient reuptake of cytosolic Ca 2+ [ 4 ]. | PMID 31028775 | 0.85 |
| However, SERCA2 is reversibly inhibited by phospholamban (PLN); phosphorylation of PLN at serine 16 and threonine 17 reverses this inhibition. | PMID 31817415 | 0.85 |
| Until phosphorylated, PLN inhibits the SR ATPase (SERCA2) from transporting calcium back into the SR, with greater inhibition by the DCM-associated variants. | PMID 35617362 | 0.85 |
| The RYR2 Ser2814 and PLN Ser16,Thr17 events are linked to increased flux of calcium through the SR, with RYR2 Ser2814 associated with channel opening and augmented outward flux, while PLN Ser16,Thr17 has been shown to increase inward flux by releasing PLN inhibition of ATP2A2 ( xref ) [ xref , xref ]. | PMID 36902152 | 0.84 |
| Phosphorylation of both the protein kinase A (PKA) site Ser‐16 and the CaMKII site Thr‐17 relieves the PLB inhibition of SERCA2 and thus increases its capacity to remove cytosolic Ca 2+ . | PMID 29431258 | 0.84 |
| These results strongly support a direct regulation of JNK2 in enhanced SERCA2 function independent of PLB, but do not preclude an additional JNK2 effect on the PLB-SERCA2 interaction, in a manner that partially relieves PLB-dependent inhibition of the SERCA2 function. | PMID 33334123 | 0.84 |
| The RYR2 and PLN events are linked to increased flux of calcium through the SR, with RYR2 associated with channel opening and augmented outward flux, while PLN has been shown to increase inward flux by releasing PLN inhibition of ATP2A2 (Supplementary Table S10A) [73,74]. | PMID 36902152 | 0.84 |
| In the dephosphorylated state, PLN binds to and inhibits SERCA2. | PMID 33049962 | 0.83 |
| In resting conditions SERCA2 is inhibited by unphopshorylated PLN. | PMID 24704321 | 0.82 |
| The unphosphorylated form of PLB inhibits SERCA2 activity, whereas the phosphorylated form of PLB dissociates from inhibitor leading to increased pumping activity. | PMID 32714085 | 0.82 |
| SERCA2 is critically regulated by the 52 amino acid SR membrane phosphoprotein, phospholamban; in its dephosphorylated state, phospholamban is an endogenous inhibitor of SERCA2. | PMID 16460751 | 0.81 |
