這個基因編碼一個核絲氨酸/蘇氨酸激酶，最初在擬南芥中被鑒定出來。編碼蛋白被認為通過調節組蛋白H3/H4伴侶蛋白的水平來調節細胞周期S期染色質的裝配。這種蛋白與輻射引起的DNA損傷的雙鏈斷裂修復有關。該基因的假基因存在于染色體10和17上。交替剪接導致多個轉錄變體。
This gene encodes a nuclear serine/threonine kinase that was first identified in Arabidopsis. The encoded protein is thought to function in the regulation of chromatin assembly in the S phase of the cell cycle by regulating the levels of a histone H3/H4 chaperone. This protein is associated with double-strand break repair of DNA damage caused by radiation. Pseudogenes of this gene are present on chromosomes 10 and 17. Alternate splicing results in multiple transcript variants.
