Top row: ROS in myoctes which have been exposed to adenovirus without the UCP2 protein. Increased DCF fluorescence can be seen over time, representing the presence of a significant level of ROS. Bottom row: ROS in a myocytes exposed to an adenovirus producing the UCP2 protein.DCF fluorescence is barely visible, representing little to no ROS presence. | Top row: ROS in myoctes which have been exposed to adenovirus without the UCP2 protein.

In this model of UCP2, the light sea green parts represent the alpha helices which are thought to be involved in the transport of protons. All negatively charged amino acids, glutamic and aspartic, are colored crimson. These may be involved in the direct transport of protons through UCP2. All positively charged amino acids, except for Lys141 and Arg185, are colored navy. These may be involved in the transport of deprotonated fatty acid molecules through UCP2, as well. Lys141 and Arg185, which are speculated to bind to the UCP2 inhibitor, GDP, are colored light sky blue. Helix sequences, conserved between different UCP proteins, which may also have a role in fatty acid transport, are colored orange. Helices found in the matrix or the inter-membrane space are colored light aquamarine. Loops, which aren’t involved in the active site, are colored white. '> | ||
