摘要：

We have cloned and sequenced a homologue of the ring-infected erythrocyte surface antigen (RESA) gene from Plasmodium falciparum designated RESA-2. Two reading frames with high homology to exon 1 and exon 2 of RESA at both the nucleotide and amino acid levels were identified in the RESA-2 sequence. However, RESA-2 does not contain either of the blocks of tandem repeats present in RESA. The lack of an RNA transcript in either asexual or sexual stage parasites and the presence of an in-frame stop codon in the second reading frame suggests RESA-2 could be a pseudogene. Its lack of expression in asexual stages demonstrates that it does not complement the RESA deletion in isolate FCR3.
