Figure 6From: GPR50 is the mammalian ortholog of Mel1c: Evidence of rapid evolution in mammalsAlignment of the repeated heptad found in the C-terminal extension of human GPR50 and comparison with the repeated heptad observed in the C-terminal domain (CTD) of RNA polymerase II (RNAPII). The three positions (2, 5 and 7) occupied by phosphorylable serine residues in RNAPII CTD are boxed.Back to article page
