Atm phosphorylated creb in vitro and in vivo in response to ionizing radiation (ir) and h(2)o(2) on a stress-inducible domain. Ir-induced phosphorylation of creb correlated with a decrease in creb transactivation potential and reduced interaction between creb and its transcriptional coactivator, creb-binding protein (cbp). A creb mutant containing ala substitutions at atm phosphorylation sites displayed enhanced transactivation potentialit is, therefore, likely that atm and atr regulate creb phosphorylation collectively in response to stress stimuli.

Phosphorylation of cAMP-specific PDE4A5 (phosphodiesterase-4A5) by MK2 (MAPKAPK2) attenuates its activation through protein kinase A phosphorylation. In the present study, we show that PDE4A5 is phosphorylated at Ser147, within the regulatory UCR1 (ultraconserved region 1) domain conserved among PDE4 long isoforms, by MK2 (MAPK-activated protein kinase 2, also called MAPKAPK2). Phosphorylation by MK2, although not altering PDE4A5 activity, markedly attenuates PDE4A5 activation through phosphorylation by protein kinase A. This modification confers the amplification of intracellular cAMP accumulation in response to adenylate cyclase activation by attenuating a major desensitization system to cAMP.

Here we systematically quantified ligand-induced interactions between 148 GPCRs and all 11 unique G alpha subunit C-termini. For each receptor, we probed chimeric G alpha subunit activation via a transforming growth factor-alpha (TGF alpha) shedding response in HEK293 cells lacking endogenous Gq/11- and G12/13- signaling. | We defined positive coupling if any member of the subfamily scored LogRAi ≥ -1 and negative coupling if all of the members scored LogRAi < -1 (Figure 3A-B). ROC analysis gives AUC = 0.78 (Figure S4A) when considering high-confidence known coupling data and suggested a threshold of LogRAi ≥ -1.0 for defining true couplings. | The score associated to this interaction has a LogRAi ≥ -1.0.

TBX2 and TBX3 function as transcriptional repressors and both have been shown to inhibit myogenesis (Carlson et al, 2002; Zhu et al, 2014). Abnormal expression of TBX2 has been reported in several cancers including breast, pancreas, and melanoma, where it has been shown to drive proliferation (reviewed in Abrahams et al (2010)). As has been previously shown in other cell types, TBX2 was found to induce a downregulation of p14/19ARF and function as a direct repressor of p21 in RMS

Using synthetic peptides and mutant cell lines, we identified threonine 56, one of two consensus sites for cdc2 within the bcl-2 sequence, as a residue phosphorylated by cdc2. Mutation at threonine 56 abrogated the cell cycle inhibitory effect of bcl-2 without affecting anti-apoptotic function.Taken together, our present findings indicate that phosphorylation of bcl-2 at threonine 56 by cdc2 is required for bcl-2-mediated cell cycle inhibition, which may have some roles during mitosis in the normal cell cycle.
