To date thismachinery has been considered strictly metazoan specific.

A primarysearch to collect putative initial candidates was performed using the basiclocal alignment sequence tool (BLAST: blastp and tblastn) usingHomo sapiens
To identify distant homologsthat might have escaped these simple searches, two additional methodswere used. The same BLAST search was repeated using homologs fromnonmetazoan taxa, such asDictyostelium,Capsaspora,orAmastigomonas,as queries instead ofHomosequences. Additionally, for integrinβ, integrinα, vinculin, talin, and FAK, we performed protein...
Alignments were constructed for all proteins using theMuscl
