CC   -!- FUNCTION: Substrate-recognition component of a DCX (DDB1-CUL4-X-box) E3
CC       ubiquitin-protein ligase complex required for cell cycle control. The
CC       DCX(TRPC4AP) complex specifically mediates the polyubiquitination and
CC       subsequent degradation of MYC as part of the DesCEND (destruction via
CC       C-end degrons) pathway. The DesCEND (destruction via C-end degrons)
CC       pathway recognizes a C-degron located at the extreme C terminus of
CC       target proteins, leading to their ubiquitination and degradation. The
CC       DCX(TRPC4AP) complex specifically recognizes proteins with an arginine
CC       at the minus 3 position (R-3 motif) at the C-terminus, such as MYC,
CC       leading to their ubiquitination and degradation (By similarity). Also
CC       participates in the activation of NFKB1 in response to ligation of
CC       TNFRSF1A, possibly by linking TNFRSF1A to the IKK signalosome
CC       (PubMed:14585990). Involved in JNK activation via its interaction with
CC       TRAF2 (PubMed:16876162). Also involved in elevation of endoplasmic
CC       reticulum Ca(2+) storage reduction in response to CHRM1
CC       (PubMed:20458742). {ECO:0000250|UniProtKB:Q8TEL6,

CC   -!- PATHWAY: Protein modification; protein ubiquitination.
CC       {ECO:0000250|UniProtKB:Q8TEL6}.
CC   -!- SUBUNIT: Component of the DCX(TRPC4AP) E3 ubiquitin ligase complex, at
CC       least composed of CUL4A, DDB1, TRPC4AP/TRUSS and RBX1 (By similarity).
CC       Interacts with MYC (By similarity). Constitutively associated with
CC       TNFRSF1A (PubMed:14585990). Directly interacts with TRADD, TRAF2, CHUK,
CC       IKBKB and IKBKG (PubMed:16876162, PubMed:14585990). Interacts with
CC       TRPC1, TRPC4 and TRPC5 (PubMed:20458742).

CC       and testis. {ECO:0000269|PubMed:14585990}.
CC   -!- PTM: Phosphorylated by GSK3B; phosphorylation is required for
CC       ubiquitination. {ECO:0000250|UniProtKB:Q8TEL6}.
CC   -!- PTM: Ubiquitinated by a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-
CC       protein ligase containing SKP2, leading to its degradation.
CC       Phosphorylation by GSK3B is required for ubiquitination.
