But the new findings indicate that people with the short version may have a chronically higher background level of activity, says Canli, whose team reports its findings online this week in Proceedings of the National Academy of Sciences.
Constructs containing the amino-terminus of Teashirt3 (i.e., full-length Teashirt3, and the N-term and ZF3 fragments) showed significantly higher HDAC activity, whereas those without the amino-terminus showed background level of activity.
Although our model is generic and is not intended to accurately describe a hepatocyte per se, it indicates that positive interactions with a background level of activity of the cAMP pathway is another possible explanation of these observations.
To put these values into context, the background level of activity associated with the metal-depleted enzyme was ca. 1% of wild-type activity.
