FIG. 4.

CXXC motifs present in Cxp proteins. The amino acid sequences of Igl1 and Igl2 were aligned with six Cxp proteins using the “PileUp” program from the Wisconsin Package (version 10.1) (Genetics Computer Group). The CXXC motifs are highlighted in gray. Numbering refers to the Igl proteins. Only a selected region is shown. Nucleic acid sequences corresponding to the Cxp ORFs can be found in the GSS division of GenBank. Accession numbers for the following ORFs are as indicated: Cxp1, AZ541185; Cxp2, AZ672865; Cxp3, AZ682291; Cxp4, AZ685201; Cxp5, AZ529058; Cxp-6, AZ500184.
