    Stress Kinase Signaling in Cardiac Myocytes

    Stress-response kinases, the mitogen-activated protein kinases (MAPKs), are activated in response to the challenge of a myriad of stressors. c-jun N-terminal kinase (JNK), extracellular signal-regulated kinase...

    Functional divergence in protein (family) sequence evolution

    As widely used today to infer ‘:function’, the homology search is based on the neutral theory that sites of greatest functional significance are under the strongest selective constraints as well as lowest evol...

    Directional mutational pressure affects the amino acid composition and hydrophobicity of proteins in bacteria

    The relationship between change in genomic GC content and protein evolution in bacteria was studied by simple correlational analysis (at the genus level) and by Felsenstein’s (1985) independent contrast test. ...

    Study on the Acrtion Mechanism of Hemorrhagin I from Agkistrodon acutus Venom

    Up to now, studies on the receptor of neural toxins and their functional mechanism were extensively reported (Tu, 1977a). Receptors of neural toxins have been proved to be present in the animal’s cells. As to ...
