Comparison of the primary structures of the excretory gland peptide encoding genes whose expression profiles can be modified by byssogenic activity. The comparison was performed by using ClustalW multiple sequences alignment. The protein product encoded by the EST BG97/192_B06 is homologous to an excretory protein isolated from a filarial nematode Litomosoides sigmodontis while the rest of the EGPs encoded by selected ESTs have a salivary gland peptide from blacklegged tick (Ixodes scapularis) as their homologue. The nucleotides were colored with black when more than 50% nucleotides in this locus were identical. The gap between the nucleotides were labeled as "-".
