Additional file 4 of Uncovering missing pieces: duplication and deletion history of arrestins in deuterostomes

Maximum clade credibility tree of arrestins. Starting from the same alignment as used for Additional file 3, we constructed a phylogenetic tree with BEAST2 [94] under the Birth Death model with a relaxed molecular clock (log normal) using the gamma site model (JTT+G+I with Îą 1.04, p-invariable 0.05). The tree can be visualized with a tree viewer, e.g. Figtree [99]. (TREE 253 kb)抑制蛋白（arrestins）的最大类群置信度树。本研究沿用附加文件3所使用的序列联配，采用BEAST2软件[94]，基于出生-死亡模型搭配对数正态分布型放松分子钟，并采用γ位点替换模型（JTT+G+I，其中α=1.04、不变位点比例为0.05）构建系统发育树。该系统发育树可通过树可视化工具（如Figtree[99]）进行查看。（文件大小：253 kb）
