Upregulated expression of oncomodulin, the beta isoform of parvalbumin, in perikarya and axons in the diencephalon of parvalbumin knockout mice.
The calcium-binding proteins parvalbumin, calbindin D-28k, calretinin and calcineurin are present in subsets of GABAergic gigantic calyciform presynaptic terminals of the reticular thalamic nucleus (RTN). Previously it was hypothesized that GABA and calcium-binding proteins including parvalbumin are not only colocalized in the same neuron subpopulation, but that GABA synthesis and parvalbumin e...
متن کاملA new member of the troponin C superfamily: comparison of the primary structures of rat oncomodulin and rat parvalbumin.
When the amino-acid sequence of the 108-residue, rat tumour calcium-binding protein, oncomodulin, was aligned with that of rat muscle parvalbumin, 55 homologous positions were found, with an additional 33 single base-pair substitutions. This extensive homology, with virtual identity of the calcium-binding domains, signalled oncomodulin to be a member of the troponin C superfamily. The presence ...
متن کاملComparison of metal ion-induced conformational changes in parvalbumin and oncomodulin as probed by the intrinsic fluorescence of tryptophan 102.
The calcium-induced conformational changes of the 108-amino acid residue proteins, cod III parvalbumin and oncomodulin, were compared using tryptophan as a sensitive spectroscopic probe. As native oncomodulin is devoid of tryptophan, site-specific mutagenesis was performed to create a mutant protein in which tryptophan was placed in the identical position (residue 102) as the single tryptophan ...
متن کاملThe Enigmatic Origin of Papillomavirus Protein Domains
Almost a century has passed since the discovery of papillomaviruses. A few decades of research have given a wealth of information on the molecular biology of papillomaviruses. Several excellent studies have been performed looking at the long- and short-term evolution of these viruses. However, when and how papillomaviruses originate is still a mystery. In this study, we systematically searched ...
متن کاملA complete complementary DNA for the oncodevelopmental calcium-binding protein, oncomodulin.
RNA from a rat liver tumor (Morris hepatoma 5123tc) was used to construct cDNAs together comprising the complete coding sequence of rat oncomodulin mRNA. Information obtained from these cDNAs as well as from primer extension analysis gave a deduced length for the complete oncomodulin mRNA of approximately 680 nucleotides (excluding the poly(A) tail) including a 5'-untranslated region of 97 +/- ...
