E3 ubiquitin-protein ligase sina; E3 ubiquitin-protein ligase that is required for specification of R7 photoreceptor cell fate in the eye by mediating the ubiquitination and subsequent proteasomal degradation of Tramtrack (ttk). E3 Ubiquitin ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Acts via the formation of a complex with ebi and phyl that ubiquitinates the transcription repressor ttk, a general inhibitor of photoreceptor differentiation, in a subset of photoreceptor cel [...]

TNF-receptor-associated factor 6 (Traf6) encodes a protein that belongs to a family of adaptor proteins involved in transducing downstream signaling by interacting with cell surface receptors. It mediates the pro-inflammatory effects of Toll and related receptor signaling, and the cell death induced by JNK activation via the product of egr.

Death-associated inhibitor of apoptosis 2; Required for activation of NF-kappaB transcription factors in the immune deficiency (Imd) signaling cascade which is essential for innate immune responses upon infection by Gram-negative bacteria. Promotes cytoplasmic cleavage of Rel and its translocation to the nucleus where it drives expression of antimicrobial peptides. Binds, polyubiquitinates and activates Dredd which is required for Rel- mediated induction of antimicrobial peptides. Anti- apoptotic protein which binds, ubiquitinates and inactivates the effector caspase Drice. Suppresses [...]

Carboxy terminus of Hsp70-interacting protein; STIP1 homology and U-box containing protein 1 (STUB1) encodes a ubiquitin protein ligase involved in insulin signaling pathway regulation and protein ubiquitination.

Ubiquitin activating enzyme 1 (Uba1) encodes an E1 enzyme involved in protein ubiquitylation. It contributes to multiple processes including regulation of Ras-ERK signaling, autophagy, apoptosis and tissue growth; Belongs to the ubiquitin-activating E1 family.

Ubiquitin thioesterase otubain-like; Possible hydrolase that can remove conjugated ubiquitin from proteins in vitro and may therefore play an important regulatory role at the level of protein turnover by preventing degradation. Belongs to the peptidase C65 family.

Ubiquitin-40S ribosomal protein S27a; 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 involve [...]

Bendless (ben) encodes an E2 ubiquitin-conjugating enzyme. It plays essential roles in multiple processes such as synaptic growth and maturation, axon guidance, innate immunity, genomic integrity, tumor growth, cell invasion, apoptosis, long-term memory and escape response.

LP07794p; Ubiquitin protein ligase activity; ubiquitin-protein transferase activity; zinc ion binding. It is involved in the biological process described with: protein polyubiquitination; protein ubiquitination.
