Complete sequences of cDNA clones CC6 (WC1-6), CC7 (WC1-7), CC12 (WC1-12), CCnd1 (WC1-nd1) and CCnd2 (WC1-nd2). Deduced amino acids sequence from the coding sequences of WC1-1, WC1-2, WC1-8, and WC1-13, and the archetypal WC1 (Wc1.1) sequence were aligned using ClustalW2 and the default parameters and refined manually. GenBank accession numbers for amino acid sequences used for comparison are described in Materials and Methods. Identities are indicated by dots (.), gaps resulting from the alignment are indicated by tildes (~), gaps resulting from lack of genomic sequence (when the gaps were found adjacent and not within a coding region) are indicated by dashes (-). SRCR domains are indicated in Roman numerals and the transmembrane region is shown underlined for archetypal WC1 sequence. Continued in Figure 6.
