Simultaneous RNAi-mediated knockdown of npl-4.1 and npl-4.2 causes embryonic lethality (PubMed:16647269, PubMed:26842564). In embryos, DNA replication is partially impaired causing a delay in S phase progression in P0, AB and P1 cells; simultaneous RNAi-mediated knockdown of DNA replication checkpoint kinases chk-1 or atl-1 suppresses the delay in S phase (PubMed:18728180, PubMed:26842564). During S phase, prevents DNA replication licensing factor cdt-1 down-regulation and causes cdt-1 accumulation on mitotic chromosomes (PubMed:21981920). Impairs dissociation from the chromatin of components of the DNA replication machinery, including cdc-45, GINS complex component sld-5 and CMG helicase component mcm-3, resulting in their persistent association with chromatin throughout embryonic mitosis (PubMed:21981920, PubMed:26842564, PubMed:28368371). Abnormal ubxn-3 localization into punctate structures in the nucleus (PubMed:26842564). Reduces ufd-1 expression in embryos (PubMed:21981920, PubMed:26842564). Simultaneous RNAi-mediated knockdown of npl-4.1 and npl-4.2 in adults causes a proliferation arrest of mitotic germline cells in the gonad with formation of rad-51 foci on chromatin (PubMed:18728180). Induces the unfolded protein response and increases sensitivity to tunicamycin-induced ER stress (PubMed:16647269). Causes accumulation of misfolded protein cpl-1 in the ER (PubMed:22768338). {ECO:0000269|PubMed:16647269, ECO:0000269|PubMed:18728180, ECO:0000269|PubMed:21981920, ECO:0000269|PubMed:22768338, ECO:0000269|PubMed:26842564}. |
