該基因編碼一種蛋白質，可調節死亡相關蛋白6（daxx）的轉錄抑制活性，daxx與組蛋白脫乙酰酶、核心組蛋白和其他組蛋白相關蛋白相互作用。在小鼠中，編碼的蛋白質與macroh2a1.2的假定亮氨酸拉鏈結構域結合，macroh2a1.2是一種富含失活x染色體的變異h2a組蛋白。該蛋白的btb/poz結構域在其他蛋白質中被證明介導轉錄抑制并與組蛋白脫乙酰酶共抑制復合物的組分相互作用。該基因的選擇性剪接導致編碼相同蛋白質的多個轉錄變體。
This gene encodes a protein that may modulate the transcriptional repression activities of death-associated protein 6 (DAXX), which interacts with histone deacetylase, core histones, and other histone-associated proteins. In mouse, the encoded protein binds to the putative leucine zipper domain of macroH2A1.2, a variant H2A histone that is enriched on inactivated X chromosomes. The BTB/POZ domain of this protein has been shown in other proteins to mediate transcriptional repression and to interact with components of histone deacetylase co-repressor complexes. Alternative splicing of this gene results in multiple transcript variants encoding the same protein.
