1. Alignment of the deduced amino acid sequence of rat olfactory CNCβ1b with bovine rod CNCβ1a.
Alignment of the deduced amino acid sequence of rat olfactory CNCβ1b with bovine rod CNCβ1a. Numbersindicate positions of amino acid residues in the polypeptide. The sequence of CNCβ1a is presented starting at residue 498.Colons and periods between the two sequences indicate identical residues and conservative substitutions, respectively. Structural features similar to those of α subunits are represented by lines above the sequence.S1–S6, Membrane-spanning segments; S4, voltage sensor-like motif; P, the pore motif that lines the cavity of the channel; CaM, a nonconventional calmodulin-binding site (Weitz et al., 1998). Arrowheadindicates an exon boundary identified in human rod CNCβ1a (Ardell et al., 1996).
