1 In the present study we identified key aspartic acid residues on calstabin2 that are involved in binding to RyR2 and likely play a role in PKA phosphorylation-induced dissociation of calstabin2 from RyR2. Aspartic Acid FK506 binding protein 1b Mus musculus
2 In the present study we identified key aspartic acid residues on calstabin2 that are involved in binding to RyR2 and likely play a role in PKA phosphorylation-induced dissociation of calstabin2 from RyR2. Aspartic Acid FK506 binding protein 1b Mus musculus
3 We show that a mutant calstabin2 in which a key negatively charged residue (Asp-37) has been neutralized binds to a mutant RyR2 channel that mimics constitutively PKA-phosphorylated RyR2 (RyR2-S2808D). Aspartic Acid FK506 binding protein 1b Mus musculus
