Fig. 6. An unrooted phylogram showing the relationship between PpK_V1 (shown in bold type) and other voltage-gated K⁺ channels. Channels used in this alignment include jShak1 [AAB02603] and jShak2 [AAB02604] from the hydromedusa Polyorchis pennicilatus, the Shaker (DmK_V1 [P08510]), Shaw (DmK_V3 [P17972]) and Shal (DmK_V4 [P17971]) channels from Drosophila, one each from the squid, Loligo pealei (LpK_V2 [CAA74748]) and tunicate Halocynthia roretzi (HrK_V2 [BAA75810], and six mammalian channels, the human K_V1.5 [AAH99666] and K_V1.7 [NP 114092] channels, the mouse K_V1.4 [NP 067250], K_V3.1 [NP 032447] and K_V3.2 [NP 001020752] channels, and rabbit K_V2.2 [Q95L11] channel. Only the bipartitions supported at greater than 95% probability are shown. Scale bar represents the average number of replacements per site.
