| In response to catecholamine induced β-adrenergic signaling, PLN is phosphorylated on its cytoplasmic serine 16 residue by PKA, causing dissociation from SERCA2a. | PMID 37213226 | 0.95 |
| PLN is mainly phosphorylated by PKA at serine 16 and by CAMKII at threonine 17. | PMID 22453987 | 0.93 |
| PLN is a critical regulator of sarcoplasmic reticulum Ca 2+ -ATPase (SERCA) activity and is directly phosphorylated by PKA at serine 16. | PMID 30062182 | 0.93 |
| The PKA phosphorylation of PLB at serine 16 was also reduced in the isoproterenol‐infused hearts, together with reduced SERCA2a protein expression (Figure 2E through 2F). | PMID 38860414 | 0.91 |
| PKA dependent phosphorylation of PLB at serine 16 does not translate into an increase in SR Ca 2+ load in EPI cells. | PMID 19027024 | 0.90 |
| 15 Conversely, inhibition of PI3K signaling does not appear to have any effect on beta 1 -receptor mediated PLB phosphorylation at serine 16 by cAMP and PKA. | PMID 19365773 | 0.90 |
| Equilibrium measurements of PLB oligomerization have shown that PLB pentamers are stabilized by PKA phosphorylation of serine 16 of PLB (21), which occurs as an outcome of adrenergic signaling during physiological stress. | PMID 35605666 | 0.90 |
| The regulation of phospholamban activity is better studied in cardiac muscle: it has been shown that the phosphorylation of phospholamban at the 16 serine residue and 17 threonine residue by protein kinase A and calcium-dependent protein kinase II, respectively, leads to inactivation of phospholamban and the activation of SERCA [72,73]. | PMID 35805949 | 0.90 |
| The significance of PLN phosphorylation at serine 16 (Ser16) by PKA and threonine 17 (Thr 17) by CaMKII has been demonstrated through the detailed characterization of PLN-mutant mouse models XREF_BIBR, XREF_BIBR, XREF_BIBR, XREF_BIBR. | PMID 24244723 | 0.90 |
| The regulation of phospholamban activity is better studied in cardiac muscle: it has been shown that the phosphorylation of phospholamban at the 16 serine residue and 17 threonine residue by protein kinase A and calcium-dependent protein kinase II, respectively, leads to inactivation of phospholamban and the activation of SERCA [ xref , xref ]. | PMID 35805949 | 0.90 |
| In our in vitro model, PKA-specific phosphorylation of PLB at Serine 16 was not different upon acute ATX-II treatment as compared to the control and did not alter between genotypes (see Table 1). | PMID 39077112 | 0.90 |
| Addition of PKA and resultant serine phosphorylation of PLB appears to aid further phosphorylation by a Ca 2+ / CaM dependent kinase associated with the SR.. | PMID 10518028 | 0.89 |
| PLB can be phosphorylated by protein kinase C at serine-10, by protein kinase A (PKA) at serine-16 and by Ca 2+ /calmodulin-dependent kinase (CaMKII) at threonine-17 [3] . | PMID 15350852 | 0.89 |
| PLN is a negative regulator of SERCA 118 but PLN phosphorylation by PKA (at serine 16) or CaMKII (at threonine 17) can reduce the inhibitory efficacy of PLN, leading to increased SERCA activity. | PMID 22679140 | 0.89 |
| Thus, protein kinase A can phosphorylate phospholamban at serine residue 16 leading to increased SERCA2A activity resulting in accelerated relaxation and increased calcium uptake into the SR ( Kranias & Solaro, 1982; Li, DeSantiago, Chu, Kranias, & Bers, 2000 ). | PMID 28223225 | 0.88 |
| Upon β-adrenergic stimulation, the PKA anchored by AKAP18δ becomes activated and promotes the phosphorylation of PLB on serine 16 located on its cytoplasmic N-terminal extension ( Figure 2 B) [ 16 • ]. | PMID 18165153 | 0.87 |
| PLB phosphorylation by protein kinase A (PKA) at serine 16 (Ser16-PLB) and by CaMKII at threonine 17 (Thr17-PLB) functionally enhances Serca2a Ca 2+ uptake. | PMID 22963383 | 0.87 |
| When PLN is phosphorylated at serine 16 by protein kinase A (PKA) or at threonine 17 by Ca /calmodulin-dependent protein kinase II (CaMKII), the PLN-mediated inhibition of SERCA is relieved, leading to an increase in SERCA activity and calcium uptake. | PMID 39120296 | 0.87 |
| When cAMP is increased, cAMP-dependent protein kinase phosphorylates phospholamban at the amino acid serine 16 (Hamstra et al. 2020). | PMID 37354216 | 0.86 |
| Protein kinase A (PKA) as well as the Ca 2+ / calmodulin dependent protein kinase IIdelta (CaMKIIdelta) is able to phosphorylate PLB at specific residues (serine 16 and threonine 17, respectively) and thereby abandon its inhibitory effect on SERCA2a. | PMID 22932727 | 0.85 |
| Phosphorylation of PLB by PKA occurs at Serine 16, which is located within the region of the AKAP7delta and gamma binding site. | PMID 26027516 | 0.85 |
