Proteins & Peptides

Cyclin C is a member of the cyclin family of proteins and interacts with the cyclin-dependent kinase 8 (CDK8) and induces the phosphorylation of the carboxy-terminal domain of the large subunit of RNA polymerase II. The mRNA levels of Cyclin C fluctuate during the cell cycle and peak at the G1 phase. Cyclin C acts as a critical regulator of the G0/G1 transition of human Hematopoietic stem cells (1). Cyclin C can also combine with CDK3 to stimulate Rb phosphorylation at S807/811 during the G0/G1 transition, and this phosphorylation is required for cells to exit G0 efficiently (2). Cyclin C Protein is ideal for investigators involved in Signaling Proteins, Cell Cycle Proteins, Cancer, and Cell Cycle research.

Cyclin E1 belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle that functions as regulators of CDK kinases. Cyclin E1 activity is required for centrosome duplication during S phase and this mechanism could coordinate centrosome reproduction with cycles of DNA synthesis and mitosis (1). The downregulation of cyclin E-CDK2 kinase activity following the G1/S-phase transition that is necessary for the maintenance of karyotypic stability. Cyclin E also has a modular centrosomal-targeting domain which is essential for promoting S phase entry in a Cdk2-independent manner (2).

Cyclin H is related to the highly conserved cyclin family. Cyclin family members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Cyclin H forms a complex with CDK7 kinase and the ring finger protein MAT1 which is able to phosphorylate CDK2 and CDC2 kinases and thus act as a CDK-activating kinase (CAK) (1). Cdk-activating kinase complex is a component of human transcription factor TFIIH and plays an important role in the processes of transcription, DNA repair, and cell cycle progression (2).

CyclinK is a member of the cyclin family which can regulate transcription through their association with and activation of cyclin-dependent kinases (CDK). The CDK/CyclinK complex can phosphorylate the C-terminal domain (CTD) of the large subunit of RNA polymerase II (1). CyclinK is associated with potent CTD kinase and CDK kinase activities in vitro and coimmunoprecipitates with POLR2A. CyclinK is a new member of the transcription cyclin family which may play a dual role in regulating CDK and RNA polymerase II activities (2).

Cyclin O belongs to the highly conserved cyclin family. These family members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclin O plays an important role in the processes of transcription. Cyclin O also plays an important role in DNA repair and cell cycle progression. Cyclin O localizes exclusively in the nucleus (1). Cyclin O shows significant uracil-DNA glycosylase activity in which the activity of in vitro translated UDG2 was not as robust as that of the mitochondrial isoform of UNG (2). Cyclin O Protein is ideal for investigators involved in Signaling Proteins, Cell Cycle Proteins, Cancer, and Cell Cycle research.
