Interaction of plasma gelsolin with tropomyosin.

Abstract:

:Horse plasma gelsolin labelled with benzophenone-4-isothiocyanate can be photochemically cross-linked to rabbit cardiac tropomyosin. The cross-linking proceeds with greater efficiency in calcium-containing buffers. Further evidence for interaction between these proteins is provided by retention of fluorescently labelled gelsolin on tropomyosin-agarose affinity columns and by the ability of tropomyosin to cause an increase in the fluorescence intensity of gelsolin labelled with fluorescein-5-isothiocyanate. Both of these effects require the presence of calcium ions.

  • Characterization of a late gene, ORF67 from Bombyx mori nucleopolyhedrovirus.

    abstract::Open reading frame 67 of Bombyx mori nucleopolyhedrovirus (BmORF67) is a homologue of Autographa californica multiple NPV ORF81. The gene is conserved among all baculoviruses and is thus considered a baculovirus core gene. The transcript of BmORF67 was detected at 18-72 h post-infection (p.i.). Polyclonal antiserum ra...
