Figure 2 From: Candidate chemoreceptor subfamilies differentially expressed in the chemosensory organs of the mollusc Aplysia Analysis of candidate Aplysia californica chemosensory receptors subfamily a. (a) Conservation of predicted amino acid sequences for 10 full-length genes is displayed as a consensus strength as color-coded histogram. In this representation, the relative frequency with which an amino acid appears at a given position is reflected by the color, as depicted by the scale bar. The seven transmembrane domains (based on the HMMTOP version 2.0 program) are indicated by a solid bar above the sequence. (b) Schematic representation of the genome organization of clustered genes, partial AcCR14a and full-length AcCR27a (genomic contig AASC01105652), including predicted start (ATG) and stop codons (TAG) and intron/exon structure of AcCR27a leading to the mature multi-transmembrane protein. Met, methionine. (c) Comparative amino acid alignment of AcCR14a and AcCR27a. Identical amino acids are highlighted in black. Putative intracellular (IC), extracellular (EC), N-terminus and C-terminus domains are shown. Arrow indicates the intron/exon boundary; asterisks show potential N-linked glycosylation sites; black circles represent highly conserved cysteines.Back to article page
