... analysis of the structure of the latter made it possible to improve the currentknowledge of the mammalian PR48 cDNA. To extend thesefindings, the genomic structures of the human PR130 and PR48 ... Barbanti-Brodano, G., Russo, G. &Negrini, M. (2000) Low frequency of alterations of the a(PPP2R1A-) and b (PPP2R1B) isoforms of the subunit A of the serine-threonine phosphatase 2A in human neoplasms. ... different classes of cDNAs were isolated and analysed. The first is the Xenopus orthologue of PR130, the second proved to be a novel splice variant and the third is the Xenopus orthologue of PR48. Moreover,...
