The phosphatase pac1
WebbPA-8 is a potent, selective and orally active PACAP type I (PAC1) receptor antagonist. PA-8 inhibits the phosphorylation of CREB induced by PACAP in PAC1 -, but not VPAC1- or VPAC2-receptor. PA-8 also inhibits PACAP-induced cAMP elevation with an IC50 of 2 nM. For research use only. We do not sell to patients. PA-8 Chemical Structure WebbMitogen-activated protein kinases (MAPKs) are activated by various stimuli, such as growth factors, cytokines, or stress, and are considered to be important mediators in intracellular signal transduction networks.

WebbHere we show that during apoptosis, p53 activates transcription of PAC1 by binding to a palindromic site in the PAC1 promoter. PAC1 transcription is induced in response to serum deprivation and oxidative stress, which results in p53-dependent apoptosis, but not in response to γ-irradiation, which causes cell cycle arrest5,6. raymond babiczWebbPAC-1 deficiency led to increased activity of Jun kinase (Jnk) but unexpected impairment of the activity of extracellular signal-regulated kinase (Erk) and the kinase p38, reduced … raymond bacharachWebb1 jan. 2007 · Bhalla US, Ram PT, Iyengar R (2002) MAP kinase phosphatase as a locus of flexibility in a mitogen-activated protein kinase signaling network.
