pole4是一种组蛋白折叠蛋白，与其他组蛋白折叠蛋白相互作用，以序列独立的方式结合DNA。这些组蛋白折叠蛋白二聚体结合在较大的酶复合物中，用于DNA转录、复制和包装。
POLE4 is a histone-fold protein that interacts with other histone-fold proteins to bind DNA in a sequence-independent manner. These histone-fold protein dimers combine within larger enzymatic complexes for DNA transcription, replication, and packaging.
