Summaries for CDT1 Gene

Entrez Gene Summary for CDT1 Gene

  • 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]

GeneCards Summary for CDT1 Gene

CDT1 (Chromatin Licensing And DNA Replication Factor 1) is a Protein Coding gene. Diseases associated with CDT1 include meier-gorlin syndrome 4 and meier-gorlin syndrome 1. Among its related pathways are Cell Cycle, Mitotic and Cell Cycle, Mitotic.

UniProtKB/Swiss-Prot for CDT1 Gene

  • 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.

Post-translational modifications for CDT1 Gene

  • 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.
  • 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.
  • Modification sites at PhosphoSitePlus
  • Ubiquitination at Lys24, Lys166, Lys189, Lys240, and Lys377

Disorders for CDT1 Gene

  • Meier-Gorlin syndrome 4 (MGORS4) [MIM:613804]: 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. {ECO:0000269 PubMed:21358631, ECO:0000269 PubMed:21358632}. Note=The disease is caused by mutations affecting the gene represented in this entry.
