A. Alignment of the partial zebrafish kcqn4 sequence (A), with KCNQ4 sequences from chimpanzee (B), frog (C) and human (D). The sequences on top of the KCNQ4 groups are the translation of the sequences that we obtained from the sequencing of PCR products (Table 2). The carboxyl region that contains the sequences implicated in the assembly of homo- vs. hetero-tetramers is indicated with bars, with the Head-Linker-Tail designations. B. Alignment of the translation of the Chr 19 sequence of zebrafish Kcnq4 (A) with the amino termini of Frog (B), Chimpanzee (C) and Human (D).
