Homolog Finder

for EF-Hand Calcium-Binding Proteins

This script finds the name and number of homologous residues. It is based on the main alignment.

Enter a residue number and choose a protein/domain from the menu. For CDPK and spectrin, you may enter the residue number in either the numbering of the main alignment or in the true number from the entact protein (these numbers are shown in parentheses in the alignment). Then select the other proteins/domains in which you want to know the homologous residues.
