ARID (AT-rich interaction domain) protein is a transcription factor family in higher eukaryotes that regulates cell proliferation, development, and differentiation. Specificity of DNA binding ability in this family prefers AT-rich sequences, but some ARID family proteins are not sequence-specific DNA-binding proteins or they do not bind AT-rich sequences. We found two genes that encode ARID in Giardia lamblia genome database, garid1 and garid2. We analyzed the function of garid1 first. AU1-tagged gARID1 was found to localize to nuclei. During encystation, gARID1 mRNA level decreased emphatically, but protein level increased. We also found that gARID1 can bind AT-rich initiator of the cwp1 promoter by EMSA. Mutation analysis revealed gARID1 binding sequence was AGATC and AATAAAATA. We used ChIP to demonstrate that gARID1 can bind cwp1 gene promoter in vivo.
