Predicted to enable cullin family protein binding activity and ubiquitin protein ligase activity. Involved in several processes, including negative regulation of intracellular signal transduction; positive regulation of metaphase/anaphase transition of meiotic cell cycle; and sister chromosome movement towards spindle pole involved in meiotic sister chromatid segregation. Part of Cul2-RING ubiquitin ligase complex. Is expressed in germ line; gonad; and oocyte. Orthologous to human RBX1 (ring-box 1).
WB Description
The rbx-1 gene encodes an ortholog of the mammalian RING box protein RBX1 (or ROC1), which interacts with several cullins and is a subunit of both the von Hippel-Lindau (VHL) tumor suppressor complex and of the SCF ubiquitin-ligase (E3) complex.
