Cyclins regulate cell cycle progression by complexing with and activating cdc2 or related kinases. PRAD1/cyclin D1 is a recently discovered putative oncogene in several types of human tumors and may regulate G1-S phase progression. We have cloned a related human cDNA, called cyclin D3, from a placental cDNA library by cross-hybridization with PRAD1. In synchronized HeLa cells, the mRNA levels of PRAD1 and cyclin D3 were regulated reciprocally through the cell cycle: cyclin D3 mRNA levels peaked in S phase, where PRAD1 mRNA was lowest in S. In normal human mammary epithelial (70N) cells synchronized by growth factor deprivation and subsequent growth factor stimulation, PRAD1 expression peaked in G1 and declined before S phase, while cyclin D3 expression rose later in G1 and remained elevated in S. Therefore, the close relationship (53.1% identity) between PRAD1 and cyclin D3 does not necessarily imply redundant functions of these candidate G1 cyclins; they may have distinct roles in progression from G1 through S phase.

D011519	Proto-Oncogenes	Normal cellular genes homologous to viral oncogenes. The products of proto-oncogenes are important regulators of biological processes and appear to be involved in the events that serve to maintain the ordered procession through the cell cycle. Proto-oncogenes have names of the form c-onc.	Proto-Oncogene,Proto Oncogene,Proto Oncogenes
D003001	Cloning, Molecular	The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.	Molecular Cloning
D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D012313	RNA	A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. RNA is unique among biological macromolecules in that it can encode genetic information, serve as an abundant structural component of cells, and also possesses catalytic activity.
