Fig. 4.
Species tree with domain assignments for putative filamins. The tree is based on 31 ubiquitous proteins, as described by Cicarelli (Ciccarelli et al., 2006). The yellow boxes show CH domains and the pink boxes show filamin domains. The color intensity indicates the degree of sequence similarity to the 21st filamin domain of human filamin A, the strongest integrin binding domain. Blue boxes indicate domains other than CH and filamin domains.
