CC -!- FUNCTION: Contributes to the neddylation of all cullins by transferring
CC NEDD8 from N-terminally acetylated NEDD8-conjugating E2s enzyme to
CC different cullin C-terminal domain-RBX complexes which is necessary for
CC the activation of cullin-RING E3 ubiquitin ligases (CRLs). May play a
CC role in DNA damage response and may participate in cell proliferation
CC and anchorage-independent cell growth. {ECO:0000250|UniProtKB:Q9BTE7}.
CC -!- SUBUNIT: Part of a complex that contains DCUN1D5, CUL1 and RBX1; this
CC interaction is bridged by CUL1. Interacts (via the DCUN1 domain) with
CC the unneddylated cullins: interacts with CUL1, CUL2, CUL3, CUL4A, CUL4B
CC and CUL5; these interactions promote the cullin neddylation and the
CC identity of the cullin dictates the affinity of the interaction.
CC Interacts (via DCUN1 domain) with UBE2M (N-terminally acetylated form)
CC and probably with UBE2F (N-terminally acetylated form). May also
CC interact with regulators or subunits of cullin-RING ligases such as
CC RBX1, RNF7, ELOB and DDB1; these interactions are bridged by cullins.
CC Interacts with CAND1; this interaction is bridged by cullins and
CC strongly inhibits the neddylation of cullins. These CAND-cullin-DCNL
CC complexes can only be neddylated in the presence of a substrate
CC adapter. {ECO:0000250|UniProtKB:Q9BTE7}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9BTE7}.
CC Cytoplasm, cytoskeleton, spindle {ECO:0000250|UniProtKB:Q9BTE7}.
CC Note=Subcellular localization is independent of the interaction with
CC cullins. {ECO:0000250|UniProtKB:Q9BTE7}.
CC -!- DOMAIN: The DCUN1 domain, also known as PONY domain, mediates the
CC interaction with different cullins. The DCUN1 domain mediates the
CC interaction with the N-terminally acetylated NEDD8-conjugating E2s
CC enzyme leading to the NEDD8 transfer from N-terminally acetylated
CC NEDD8-conjugating E2s enzyme to different cullin C-terminal domain-RBX
CC complexes; the neddylation efficiency correlates with the DCUN1D5-
CC cullin and DCUN1D5-E2 interaction affinities.
CC {ECO:0000250|UniProtKB:Q9BTE7}.
CC -!- PTM: Phosphorylation at Ser-41 is independent of cullin's interaction
CC and neddylation. Phosphorylated in response to both TICAM1 and MYD88
CC dependent Toll-like receptor (TLR) pathway activation (By similarity).
CC Phosphorylated in response to IL1B stimulation (By similarity).
CC {ECO:0000250|UniProtKB:Q9BTE7, ECO:0000250|UniProtKB:Q9CXV9}.
