High impact information on PRKACB


Biological context of PRKACB

  • Of particular interest, PKA-Cbeta facilitated the intramolecular interaction of p73alpha, thereby masking the N-terminal transactivation domain with the C-terminal inhibitory domain [1].
  • Constitutive expression of PKA-Cbeta in Rat1A cells induces their transformation, and c-MYC-induced transformation can be reverted by pharmacological inhibition of PKA, suggesting that up-regulation of PKA is critical for c-MYC-associated tumorigenesis [2].
