CaPS: Calcium Pattern Search Go to Bioinformatics-Hub

This program serarch for calcium binidng sites in proteins. Please input protein sequence here using FASTA format


CaPS (Calcium Pattern Search) identifies Ca(II)-binding motifs in proteins based on unique patterns (or signatures) listed below. These patterns (or signatures) can be used to identify canonical EF-hand and pseudo EF-hand. We expect to significantly expand this list in the future to include non-contiguous (binding motif includes AA residues distant from each other in the primary structure) patterns. To check a sequence for the presence of a Ca(II)-binding signature, please past the protein sequence in the textarea and then click Search CAPS.
