Ubiquitin-60S ribosomal protein L40; [Ubiquitin]: exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is invol [...]

Ubiquitin-conjugating enzyme E2 variant 1; Involved in protein ubiquitination, but has no ubiquitin ligase activity on its own. The uev-1-ubc-13 heterodimer catalyzes the synthesis of non-canonical poly-ubiquitin chains that are linked through Lys-63. Involved in sorting Lys-63-linked polyubiquitinated maternal membrane proteins for degradation by targeting to multivesicular bodies. Required for glr-1-containing glutamate receptor trafficking in neurons. May have a role in synaptic transmission at motorneurons. May be involved in the ubiquitination and growth of intracellular polygluta [...]

Small ubiquitin-related modifier; Ubiquitin-like protein which can be covalently attached to target lysines as a monomer. Does not seem to be involved in protein degradation and may function as an antagonist of ubiquitin in the degradation process. Plays a role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduction. Covalent attachment to its substrates requires prior activation by the E1 complex aos-1-uba-2 and linkage to the E2 enzyme ubc-9, and can be promoted by an E3 ligase such as gei-17. Required for embryonic dev [...]

Anaphase-promoting complex subunit 11; Probable component of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated E3 ubiquitin ligase that controls progression through mitosis and the G1 phase of the cell cycle. The APC/C complex acts by mediating ubiquitination and subsequent degradation of target proteins. Developmental role in early embryogenesis and the metaphase to anaphase transition in meiosis and mitosis. In vitro, recruits the ubiquitin-conjugating enzyme ubc-2 to exert ubiquitin ligase activity. Belongs to the RING-box family.
