Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
Differential syn thesis of mRNA	95	Network	kinetics, compartment_1, compartment_2
The model consists of three major pathways: Calcium-calmodulin dependent protein kinase IV (CaMKIV), Mitogen-activated protein kinase (MAPK) and Protein Phosphatase 1 (PP1). Each of these converged on CREB activation. We also modeled further interactions with Transducer of regulated CREB activity 1 (TORC1) and the protein kinase A (PKA) pathway.
