该基因编码聚腺苷二磷酸核糖基转移酶样1蛋白，能催化聚腺苷二磷酸核糖基化反应。该蛋白具有与聚adp-核糖基转移酶同源的催化结构域，但缺乏激活聚adp-核糖基转移酶c端催化结构域的n端dna结合结构域。由于该蛋白不能直接与dna结合，其转移酶活性可能被其他因素激活，如广泛的羧基末端介导的蛋白质-蛋白质相互作用。[由RefSeq提供，2008年7月]
This gene encodes poly(ADP-ribosyl)transferase-like 1 protein, which is capable of catalyzing a poly(ADP-ribosyl)ation reaction. This protein has a catalytic domain which is homologous to that of poly (ADP-ribosyl) transferase, but lacks an N-terminal DNA binding domain which activates the C-terminal catalytic domain of poly (ADP-ribosyl) transferase. Since this protein is not capable of binding DNA directly, its transferase activity may be activated by other factors such as protein-protein interaction mediated by the extensive carboxyl terminus.
