Basic Local Alignment Search Tool (BLAST)

 

A BLAST search was used in order to find similar proteins to Tau. The search allows the discovery of sequences with regions of similarity between proteins and calculates the statistical significance of matching regions. The E-value generated gives a statistical value of how probable it is that two sequences were matched together purely by chance. E-values close to 0 shows that a sequence match is near ‘perfect’ and thus significantly related.
