title: Mutational analysis identifies a five base pair cis-acting sequence essential for GBP130 promoter activity in Plasmodium falciparum.
abstract: Here we describe the functional characterization of a Plasmodium falciparum promoter region, identifying a discrete five base pair sequence element that is responsible for efficient promoter activity. This sequence element binds nuclear factors in a sequence-specific manner. It shares no homology with any known eukaryotic transcription factor binding site, supporting the notion that the protozoan parasite P. falciparum has evolved a transcriptional machinery distinct from that of its human and mosquito hosts. This report represents the first description of a minimal and necessary cis-acting sequence element for efficient promoter activity in P. falciparum.
