Human Gene CDT1 (uc002flu.3) Description and Page Index
  Description: Homo sapiens chromatin licensing and DNA replication factor 1 (CDT1), mRNA.
RefSeq Summary (NM_030928): The protein encoded by this gene is involved in the formation of the pre-replication complex that is necessary for DNA replication. The encoded protein can bind geminin, which prevents replication and may function to prevent this protein from initiating replication at inappropriate origins. Phosphorylation of this protein by cyclin A-dependent kinases results in degradation of the protein. [provided by RefSeq, Mar 2011].

DESCRIPTION: RecName: Full=DNA replication factor Cdt1; AltName: Full=Double parked homolog; Short=DUP;
FUNCTION: Cooperates with CDC6 to promote the loading of the mini- chromosome maintenance complex onto chromatin to form the pre- replication complex necessary to initiate DNA replication. Binds DNA in a sequence-, strand-, and conformation-independent manner. Potential oncogene.
SUBUNIT: Interacts with GMNN; inhibits both binding of the MCM complex to origins of replication and DNA-binding activity. Interacts with PCNA.
INTERACTION: Q99741:CDC6; NbExp=3; IntAct=EBI-456953, EBI-374862; O75496:GMNN; NbExp=8; IntAct=EBI-456953, EBI-371669; Q14566:MCM6; NbExp=3; IntAct=EBI-456953, EBI-374900;
DEVELOPMENTAL STAGE: Present during G1 and early S phase of the cell cycle. Degraded during the late S, G2, and M phases.
DOMAIN: The PIP-box K+4 motif mediates both the interaction with PCNA and the recuitment of the DCX(DTL) complex: while the PIP-box interacts with PCNA, the presence of the K+4 submotif, recruits the DCX(DTL) complex, leading to its ubiquitination (By similarity).
PTM: Ubiquitinated by the DCX(DTL) complex, also named CRL4(CDT2) complex, in response to DNA damage, leading to its degradation. Ubiquitination by the DCX(DTL) complex is necessary to ensure proper cell cycle regulation and is PCNA-dependent: interacts with PCNA via its PIP-box, while the presence of the containing the 'K+4' motif in the PIP box, recruit the DCX(DTL) complex, leading to its degradation. The interaction with GMNN protects it against ubiquitination.
PTM: Phosphorylated by cyclin A-dependent kinases which results in the binding of CDT1 to the F-box protein SKP2 and subsequent degradation. Phosphorylated at Thr-29 by MAPK8/JNK1, which blocks replication licensing in response to stress. Binding to GMNN is not affected by phosphorylation.
DISEASE: Defects in CDT1 are the cause of Meier-Gorlin syndrome type 4 (MGORS4) [MIM:613804]. MGORS4 is a syndrome characterized by bilateral microtia, aplasia/hypoplasia of the patellae, and severe intrauterine and postnatal growth retardation with short stature and poor weight gain. Additional clinical findings include anomalies of cranial sutures, microcephaly, apparently low-set and simple ears, microstomia, full lips, highly arched or cleft palate, micrognathia, genitourinary tract anomalies, and various skeletal anomalies. While almost all cases have primordial dwarfism with substantial prenatal and postnatal growth retardation, not all cases have microcephaly, and microtia and absent/hypoplastic patella are absent in some. Despite the presence of microcephaly, intellect is usually normal.
SIMILARITY: Belongs to the Cdt1 family.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
