From: Structural and functional analysis of the Entamoeba histolytica EhrabB gene promoter
Transcriptional start sites of the EhrabB gene. (A) Primer extension products (PE) were analyzed alongside sequencing ladder extended with the same 18 bp primer complementary to nucleotides 85-68 downstream of the EhrabB start codon. ATG indicate the start codon. (B) Schematic representation of the genomic organization of Ehcp112 and EhrabB genes. Arrows indicate the transcription initiation sites and transcription sense for each gene. The line below shows the EhrabB 5'-flanking r egion analyzed (+96 to -683).
