CHAF1b is needed for mouse preimplantation embryos. Mus musculus strain:Kunming strain

Chromatin assembly factor-1, subunit b (CHAF1b), the p60 subunit of the chromatin-assembly factor-1 (CAF-1) complex, is an evolutionarily conserved protein that has been implicated in various biological processes. Although a variety of functions have been attributed to CHAF1b, its function in preimplantation embryos remains obscure.染色质组装因子1亚基b（Chromatin assembly factor-1, subunit b, CHAF1b）是染色质组装因子1（CAF-1）复合物的p60亚基，属于进化保守蛋白，已被证实参与多种生物学过程。尽管目前已知CHAF1b具备多种功能，但其在植入前胚胎中的功能仍不明确。
