Difference in TANGO aggregation between wild type and variant
	This graph plots the per-residue TANGO aggregation score difference between the wild type protein and this variant. From left to right, all residue TANGO score differences from the N-terminus to the C-terminus are plotted. A flat line indicates that the variant does not alter the aggregation profile of the protein. Positive peaks indicate increased aggregation tendency due to this variant. Negative peaks indicate decreased aggregation tendency due to this variant.

Molecular visualization of TANGO aggregation-prone regions
Wild type 1A02_HUMAN	Variant VAR_004343
These two molecular images show the TANGO aggregation-prone regions as red colored segments. The left image represents the wild type protein, the right represents the variant protein. If both images are the same, it implies that the introduced variant amino acid does not alter the TANGO aggregation tendency. In any other case, the images allow structural interpretation of gained or lost aggregation-prone regions due to the variant amino acid. The structural location of the variant residue is colored in yellow. Click on the images to get a larger view and to download the original.
