タイトル Regulation of germ cell development by ARI1 family ubiquitin ligases in C. elegans.
ジャーナル Sci Rep
Abstract RING-between-RING (RBR) E3 ubiquitin ligases are implicated in various developmental processes, and mutations in genes encoding RBR proteins HHARI/ARIH1 and Parkin are associated with human diseases. Here we show by phylogenetic analysis that the ARI1 family has undergone a dramatic expansion within the Caenorhabditis clade in recent history, a characteristic shared by some genes involved in germline development. We then examined the effects of deleting all ARI1 family members in the nematode Caenorhabditis elegans, which to our knowledge represents the first complete knockout of ARI1 function in a metazoan. Hermaphrodites that lacked or had strongly reduced ARI1 activity had low fecundity and were partially defective in initiation of oocyte differentiation. We provide evidence that the C. elegans ARI1s likely function downstream or in parallel to FBF-1 and FBF-2, two closely related RNA-binding proteins that are required for the switch from spermatogenesis to oogenesis during late larval development. Previous studies have shown that the E2 enzymes UBC-18/UBCH7 and UBC-3/CDC34 can functionally collaborate with ARI1 family members. Our data indicated that UBC-18, but not UBC-3, specifically cooperates with the ARI1s in germline development. These findings provide new insights into the functions of RING-between-RING proteins and Ariadne E3s during development.
