Résumé : The bovine cyclic AMP responsive binding protein cDNA (CREB2) was isolated from a Iambda-gt11 cDNA expression library using a 32P labelled oligonucleotide corresponding to the 21 bp enhancer sequence present in the BLV LTR. The deduced amino acid sequence revealed that CREB2 contains a leucine zipper structure (residue 295 to 316), a basic amino acid domain (residue 268 to 291) and several potential phosphorylation sites. © 1991 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
