Figure 1

Genomic organization of the predicted X. tropicalis FcR-like genes. The exons for each particular subtype of the Ig-like domains (D1-D6) are marked by a different color as indicated. Exons for TMs with the NxxR motif (TM1) are in black and those for the TM regions without charged residues (TM2) are in white. The gene models supported by X. tropicalis EST cDNAs are boxed. Arrows indicate transcriptional orientation. The genes are designated by their scaffold number and their consecutive position at the corresponding scaffold (version 4.1). Filled circles show position of gaps in the assembly. To conserve space, only fractions of scaffolds are shown; their borders are indicated in kb at the right and left sides.
