Sequencing strategy and exon/intron structure of
baebl. Oligonucleotides were designed based on the
genomic sequence obtained from the P.
falciparum genome project (Sanger Centre) and used for
the sequencing of genomic DNA (GenBank Accession No. AF332918) and
reverse transcription–PCR of mRNA (GenBank Accession No. AF332919) to
determine the intron/exon structure in P. falciparum
Dd2/Nm strain. (A) Schematic representation of the
gene and predicted protein structure of baebl. Predicted
protein structure has strong similarity with EBA-175, containing the
putative signal sequence (SS, amino acids 1–21) predicted by
SIGNALP V2.0; region 2 (two DBL domains, F1 and F2);
region 6 (3′Cys), the transmembrane domain (TM, amino acids
1,134–1,153) predicted by TMHMM V2.0, followed by
the putative cytoplasmic domain (Cyt). (B) f1 to f9
primers (see Materials and Methods) are used for reverse
transcription–PCR of mRNA (lanes marked c) and PCR of genomic DNA
(lanes marked g). (Bar = 1 kb.)
