In an initial comparison of the ligand positions of tetracycline, dox and atc in TetR, these ligands ... ligand in binding site II. To account for this observation, the occupancy of the ligand in binding site II was estimated at 50% and that in bind- ing site I at 100%. Wh...

... activation ⁄ inhibition of adenylyl and guanylyl cyclases, and the opening and closing of ion channels. In this review, we shall investigate the ability of GPCRs to activate Akt signaling pathways ... a multiprotein complex that includes b-arrestin, protein phosphatase 2A and Akt. Protein phosphatase 2A inactivates Akt, thereby relieving Akt’s inhibition of glycogen synthase kinase...
