c-Fos is a member of the AP-1 transcription factor family under the Fos protein family umbrella, alongside Fra-1, Fra-2 and Fos-B. Also in the AP-1 transcription family are the Jun proteins, c-Jun, Jun-B and Jun-D. Each member of the AP-1 transcription family is a phosphonuclear protein composed of a carboxy-terminal leucine zipper domai
AKT1 is a serine/threonine protein kinase with homology to protein kinase A (PKA) and protein kinase C (PKC). AKT1 contains the central kinase domain sandwiched between a pleckstrin homology domain and a regulatory domain (1). AKT1 is regulated by receptor tyrosine kinase pathways and is activated in a PI3K-dependent manner following growth factor stimulation (1).
