Figure 1.
Expression and sequence of Cha. (a) Nucleotide and deduced aa sequence of Cha. The aa positions are denoted by numbers in boldface; the asterisk indicates the termination codon (TGA). (b) Cha mRNA Northern blot analysis. Nylon membranes containing 2 μg of each poly(A)+ RNA from various human tissues were hybridized with a Cha cDNA probe. (c) An aa comparison of human and mouse Cha peptides with T. cruzi antigens. Identical aa’s are denoted by two dots and conserved aa by one dot. Percentages of homology are shown. The open box indicates a SAPA COOH-terminal repeat.
