Fig. 2. Phylogenetic analysis of GRASP proteins across the eukaryotic tree of life. This unrooted neighbour-joining tree is based on 53 protein sequences and was estimated from an alignment of GRASP N-terminal domains (370 amino acids). Numbers at branches indicate statistical support (bootstrap of 300 replicates) of >50% in the corresponding consensus tree. The insects and deuterostomia branch is shown at a magnified scale.
