Summary: Predicted to enable protein-macromolecule adaptor activity and ubiquitin protein ligase binding activity. Involved in several processes, including anaphase-promoting complex-dependent catabolic process; male germ-line sex determination; and meiotic chromosome segregation. Located in cytoplasm and nucleus. Part of Cul2-RING ubiquitin ligase complex. Is expressed in several structures, including P1; P10; P11; germ line; and nerve ring. Orthologous to human CUL2 (cullin 2). [provided by Alliance of Genome Resources, Dec 2024]

CUL-2(LRR-1) and UBXN-3 drive replisome disassembly during DNA replication termination and mitosis.
Title: CUL-2(LRR-1) and UBXN-3 drive replisome disassembly during DNA replication termination and mitosis.
CUL-2 RING E3 ubiquitin-ligase acts at multiple levels to control germline development; CUL-2 may similarly regulate germline development in other organisms as well.
Title: CRL2(LRR-1) E3-ligase regulates proliferation and progression through meiosis in the Caenorhabditis elegans germline.
Results indicate that LRR-1 acts as a nuclear substrate-recognition subunit of a Cullin 2-RING E3 ligase complex (CRL2(LRR-1)), which ensures DNA replication integrity.
Title: The CRL2LRR-1 ubiquitin ligase regulates cell cycle progression during C. elegans development.
The C. elegans p97/CDC-48-UFD-1-NPL-4 complex controls the sperm-oocyte switch by regulating CUL-2-mediated TRA-1A proteasome degradation.
Title: Caenorhabditis elegans p97 controls germline-specific sex determination by controlling the TRA-1 level in a CUL-2-dependent manner.
MEL-26 levels are kept low by the action of another type of ubiquitin ligase, which contains CUL-2
Title: Levels of the ubiquitin ligase substrate adaptor MEL-26 are inversely correlated with MEI-1/katanin microtubule-severing activity during both meiosis and mitosis.
Fem-1 protein is a substrate-specific adaptor for a CUL-2-based ubiquitin ligase.
Title: PAR-6 levels are regulated by NOS-3 in a CUL-2 dependent manner in Caenorhabditiselegans.
segregation of the germ plasm involves both stabilization of germline proteins in the germ line and cullin-dependent degradation in the soma
Title: Exclusion of germ plasm proteins from somatic lineages by cullin-dependent degradation.
Results establish that zyg-11 and the cullin cul-2 promote the metaphase-to-anaphase transition and M phase exit at meiosis II in Caenorhabditis elegans.
Title: Zyg-11 and cul-2 regulate progression through meiosis II and polarity establishment in C. elegans.
Data show that inactivation of ZYG-11 produces meiotic and polarity reversal defects similar to those observed in CUL-2 mutants, suggesting that the two proteins function in the same pathways.
Title: CUL-2 and ZYG-11 promote meiotic anaphase II and the proper placement of the anterior-posterior axis in C. elegans.
oocyte maturation from pachytene exit and MPK-1 activation are redundantly controlled by the RBX-2-CUL-5- and RBX-1-CUL-2-based complexes.
Title: C. elegans RBX-2-CUL-5- and RBX-1-CUL-2-based complexes are redundant for oogenesis and activation of the MAP kinase MPK-1.
