摘要
Until recently, poly(ADP-ribosyl)ation was supposed to he confined only to polymerizing(ADP-ribosyl)transferase/(ADP-ribose)polymerase (E.C. 2.4.2.30), Here, we present novel polymerizing(ADP-ribosyl)transferase homologues from mouse and man that lack all of the N-terminal DSA binding and BRCA1 C-terminus domains and will be designated polymerizing(ADP-ribosyl)transferase-2 as distinguished from the classical polymerizing(ADP-ribosyl)transferase (polymerizing(ADP-ribosyl)transferase-1). The murine polymerizing(ADP-ribosyl)transferase-2 gene shares three identical intron positions with its Caenorhabditis elegans (EMBL nucleotide sequence database Z47075) and one with the Arabidopsis thaliana homologue ('APP', GenBank database AF069298), Expression of the murine polymerizing(ADP-ribosyl)transferase-2 gene was elevated in spleen, thymus and testis and the corresponding poly(ADP-ribosyl)ation activity might account for most of the residual poly(ADP-ribosyl)ation observed in polymerizing(ADP-ribosyl)transferase-1(-/-) mice.
