| As shown in xref , we could confirm an interaction between obscurin Ig58 or Ig58-Ig59 and phospholamban in vitro . | PMID 33438037 | 0.91 |
| The direct binding between obscurin-Ig58/59 and PLN and their enhanced association in the presence of the R4344Q variant was recently corroborated by Fukuzawa and colleagues, reporting a ~ 2.5-fold decrease in the K ; yet, the physiological relevance of the obscurin/PLN interaction was questioned (7). | PMID 37304957 | 0.91 |
| Our previous work demonstrated that wild-type obscurin binds to PLN modestly, but this interaction is markedly enhanced in the presence of the R4344Q mutation ( xref ). | PMID 32528308 | 0.85 |
| More recently, a homozygous R4344Q knock-in mouse created by the Kontrogianni–Konstantopulous group developed cardiac arrhythmias under sedentary conditions and a DCM-like phenotype upon pressure overload, which the authors attributed to an increase in the affinity, as judged by co-immunoprecipitation, for a newly identified interaction between obscurin and phospholamban, a small inhibitory peptide of the SERCA pump in the SR membrane ( xref ). | PMID 33438037 | 0.83 |
