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.

ARID(AT-rich interaction domain)蛋白质家族是真核生物的一种转因子，在许多同种的真核生物有它的同源基因，这个家族的蛋白质通常与调控细胞的生长、发育和分化的作用有关，而这个家族的蛋白质和DNA的结合能，各种ARID蛋白质的专一性尽相同，过大致上偏好於和AT-rich的序结合；我们已经在形鞭毛虫的基因组中找到个含有ARID 的基因，分别是garid1和garid2，我们首先对於garid1做分析；将AU1标记接到gARID1转染形鞭毛虫，用免疫萤光染色可发现gARID1存在於细胞核中。gARID1的讯息RNA在囊体化后会明显下，过其阳性染色和蛋白质表现有明显增加；EMSA实验中也发现gARID1会明显的与cwp1基因启动子之AT-rich initiator结合，经由突变序分析，也显示gARID1的结合序为AGATC和AATAAAATA，随后我们也用ChIP证明gARID1在细胞内也的确会和cwp1基因的启动子结合。
