Phylogenetic maximum likelihood trees of the PYG and RIN gene families. The glycogen phosphorylase (PYG) and Ras and Rab interactor (RIN) gene families are neighboring families of the SSTR1, -4 and -6 chromosomal regions. Monophyletic subtype clusters including both tetrapod and teleost sequences are indicated by bars to the right. Chromosomal or genomic scaffold assignments of the family members are indicated next to species names. Lowercase a and b are used to distinguish sequences located on the same chromosomes. Branch support values (bootstrap replicates) for deep divergences are shown at the nodes. The trees were rooted with the identified fruit fly sequences. All neighboring gene family trees for the SSTR1, -4 and -6-bearing regions, including NJ analyses and all branch support values, are shown in Figures S4-S20 (see Additional file 5).
