Several CDK2-bound genes have also been implicated in other aspects of germ cell development, including Palb2 (Simhadri et al., 2014; Hartford et al., 2016), Pds5b (Zhang et al., 2007), Safb1 (Ivanova et al., 2005), and Herc4 (Rodriguez and Stewart, 2007), or have been investigated as potential markers of infertility in human populations: Mtrr (Lee et al., 2006; Liu et al., 2015a) and Vdac3 (Pan et al., 2017b). Here, HERC4 is linked to Infertility.
