The enzyme digest analysis shows that the arm repeats of c - terminal are conceivably conservative domain . in arc1 protein , there are some active sites including n - glycosylation sites , camp - and cgmp - dependent protein kinase phosphorylation sites , protein kinase c phosphorylation sites , casein kinase ii phosphorylation sites , tyrosine kinase phosphorylation sites , n - myristoylation sites , amidation sites and leucine zipper pattern . it probably take part in the signaling process of self - incompatibility 同时在arc1蛋白质中还发现了拉链结构和多个磷酸化位点，包括camp和cgmp依赖的蛋白激酶磷酸化位点、蛋白激酶c磷酸化位点、酪蛋白激酶磷酸化位点、酪氨酸激酶磷酸化位点、糖基化位点等，拉链结构为arc1蛋白之间及与其它蛋白的相互作用提供了可能，而磷酸化位点是arc1参与信号传导过程所必需的。
