| This is a model of the canonical cAMP signaling pathway: Ligand->Receptor->G-protein->Cyclase->cAMP->PKA. It also includes phosphodiesterases to balance out cAMP formation.Bhalla US Methods Enzymol. 2002;345:3-23 | |||
PKA-inhibitor acting as a Molecule in cAMP_pathway Network
| Name | Accession Name | Pathway Name | Initial Conc. (uM) | Volume (fL) | Buffered | |
| PKA-inhibitor | cAMP_pathway Accession No. : 25 | PKA Pathway No. : 135 | 0.25 | 1000 | No | |
| About 25% of PKA C subunit is dissociated in resting cells without having any noticable activity. Doskeland and Ogreid Int J biochem 13 pp1-19 suggest that this is because there is a corresponding amount of inhibitor protein. | ||||||
PKA-inhibitor acting as a Substrate in a reaction in cAMP_pathway Network
| Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated. Kd for higher order reaction are not consider. |

| This has to be set to zero for matching the expts in vitro. In vivo we need to consider the inhibition though. | |||||||
