General description

CDT1 (Chromatin Licensing and DNA replication Factor 1) is an essential component of the cell cycle machinery. It plays an important role in insuring that there is only one round of DNA replication per cell cycle. CDT1 is a known substrate of Cdk2 and Cdk4 (Liu, E. 2004). It is presented in G1 of the cell cycle and is degraded as cells enter S phase (Liu, E. 2004). In higher eukaryotes, CDT1 is known to interact with Geminin, a protein that is degraded during mitosis, that inhibits it. CDT1 is marked for degradation by two E3 ligases: SCF complex and the CUL4-DDB1 complex (Sansam, 2006).


This antibody recognizes the Cdt1.


Epitope: C-terminal half
Recombinant protein including amino acids 238-546 of human CDT1.

Geminin plays a critical role in cell cycle regulation by regulating DNA replication and serves as a transcriptional molecular switch that directs cell fate decisions. Spermatogonia lacking Geminin disappear during the initial wave of mitotic proliferation, while geminin is not...

Geminin controls proper centrosome duplication, cell division, and differentiation. We investigated the function of geminin in oogenesis, fertilization, and early embryo development by deleting the geminin gene in oocytes from the primordial follicle stage. Oocyte-specific disruption of geminin results in...

Homologous recombination (HR) maintains genomic integrity against DNA replication stress and deleterious lesions, such as double-strand breaks (DSBs). Rad51 recombinase is critical for HR events that mediate the exchange of genetic information between parental chromosomes in eukaryotes. Additionally, Rad51 and...
