unusual facts about cell cycle



Cytarabine

Its mode of action is due to its rapid conversion into cytosine arabinoside triphosphate, which damages DNA when the cell cycle holds in the S phase (synthesis of DNA).

Processivity

Because the binding of the polymerase to the template is the rate-limiting step in DNA synthesis, the overall rate of DNA replication during S phase of the cell cycle is dependent on the processivity of the DNA polymerases performing the replication.

Tim Hunt

In 2001 he was awarded the Nobel Prize in Physiology or Medicine with Leland Hartwell and Sir Paul Nurse for their discoveries regarding cell cycle regulation by cyclin and cyclin-dependent kinases.

Tribble

A family of proteins which have a variety of roles, including involvement in the control of the cell cycle in the fruit fly, was named after these fictional animals.

Bromodeoxyuridine

BrdU can be incorporated into the newly synthesized DNA of replicating cells (during the S phase of the cell cycle), substituting for thymidine during DNA replication.

CDH1

APC/C activator protein CDH1 Cell-cycle regulated activator of the anaphase-promoting complex/cyclosome (APC/C)

Mir-15 microRNA precursor family

CHEK1 is the only cell-cycle-associated gene possessing an miR-15 family binding site in its 3' UTR.

P14arf

p14ARF inhibits mdm2, thus promoting p53, which promotes p21 activation, which then binds and inactivates certain cyclin-CDK complexes, which would otherwise promote transcription of genes that would carry the cell through the Quiescence

The Rabl

Carl Rabl (1853–1917), Austrian anatomist and pioneer of cell cycle studies

Schwannomatosis

The candidate schwannomatosis gene, named SMARCB1, is a tumor suppressor gene that regulates cell cycle, growth and differentiation.

Synexpression

One simplified example of a synexpression group is the genes cdc6, cdc3, cdc46, and swi4 in yeast, which are all co-expressed early in the G-1 stage of the cell cycle.
