General annotation (Comments)
| Function | Substrate-specific adapter of a DCX (DDB1-CUL4-X-box) E3 ubiquitin-protein ligase complex required for cell cycle control, DNA damage response and translesion DNA synthesis. The DCX(DTL) complex, also named CRL4(CDT2) complex, mediates the polyubiquitination and subsequent degradation of CDT1 and CDKN1A/p21(CIP1). CDT1 degradation in response to DNA damage is necessary to ensure proper cell cycle regulation of DNA replication. CDKN1A/p21(CIP1) degradation during S phase or following UV irradiation is essential to control replication licensing. Most substrates require their interaction with PCNA for their polyubiquitination: substrates interact with PCNA via their PIP-box, and those containing the 'K+4' motif in the PIP box, recruit the DCX(DTL) complex, leading to their degradation. In undamaged proliferating cells, the DCX(DTL) complex also promotes the 'Lys-164' monoubiquitination of PCNA, thereby being involved in PCNA-dependent translesion DNA synthesis. Ref.2 Ref.9 Ref.10 Ref.12 Ref.13 Ref.14 Ref.16 Ref.18 |
| Pathway | |
| Subunit structure | Component of the DCX(DTL) E3 ubiquitin ligase complex, at least composed of CUL4 (CUL4A or CUL4B), DDB1, DTL/CDT2 and RBX1. Interacts with CDKN1A and CDT1. Ref.2 Ref.9 Ref.10 Ref.11 Ref.12 Ref.13 |
| Subcellular location | Nucleus. Nucleus membrane; Peripheral membrane protein; Nucleoplasmic side. Cytoplasm › cytoskeleton › centrosome. Note: Nuclear matrix-associated protein. Translocates from the interphase nucleus to the metaphase cytoplasm during mitosis. Ref.8 |
| Tissue specificity | Expressed in placenta and testis, very low expression seen in skeletal muscle. Detected in all hematopoietic tissues examined, with highest expression in thymus and bone marrow. A low level detected in the spleen and lymph node, and barely detectable level in the peripheral leukocytes. RA treatment down-regulated the expression in NT2 cell. Ref.1 Ref.8 |
| Developmental stage | Expressed in all fetal tissues examined, included brain, lung, liver, and kidney. Ref.1 |
| Post-translational modification | Ubiquitinated by the anaphase promoting complex/cyclosome (APC/C). Ref.8 |
| Sequence similarities | Belongs to the WD repeat cdt2 family. Contains 7 WD repeats. |
| Sequence caution | The sequence BAA91552.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAA91586.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. |
