Sequence comparison of the feline leukemia virus-C (FeLV-C) receptor (560 amino acids) and a putative D-glucarate transporter of C. elegans, the 623 amino acid C09D4.1 gene product (GenBank accession no. AF002196).

The receptor (aa 106-550) shares 44% sequence identity with the putative transporter (aa 186-617). Amino acid identities are marked with dark shading, and similarities are indicated with light shading. Predicted transmembrane regions are shown as lines over the amino acid sequence, and two potential N-glycosylation sites are marked by an asterisk.
