Description générale
The gene encoding Retinoblastoma-associated protein (RB1) is a tumor suppressor gene localized on human chromosome 13q14.2. Human recombinant RB protein (773-end) with N-terminal GST tag (GenBank Accession No. NM_000321), expressed in a E. coli expression system.
Application
Retinoblastoma-associated protein (RB1) has been used in cell activity assay. It is also used as a kinase substrate for the kinase assay and in Western blotting.
Actions biochimiques/physiologiques
Retinoblastoma-associated protein (RB1) modulates the cell cycle. It acts as a repressor of transcription mediated by E2 factor (E2F) and influences transcriptional silencing. RB1 modulates mitochondrial activities and has a role in the organisation of heterochromatin. Mutations in the gene encoding this protein have been associated with childhood retinoblastoma.
Forme physique
Formulated in 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20, 30% glycerol and 3 mM DTT.
Notes préparatoires
Thaw on ice. Upon first thaw, briefly spin tube containing enzyme to recover full content of the tube. Aliquot enzyme into single use aliquots. Store remaining undiluted enzyme in aliquots at -70°C. Note: Enzyme is very sensitive to freeze/thaw cycles.

Cyclin D1 is an essential regulator of the G1-S cell-cycle transition and is overexpressed in many cancers. Expression of cyclin D1 is under tight cellular regulation that is controlled by many signaling pathways. Here we report that PARP14, a member

The roles of CDK4 in the cell cycle have been extensively studied, but less is known about the mechanisms underlying the metabolic regulation by CDK4. Here, we report that CDK4 promotes anaerobic glycolysis and represses fatty acid oxidation in mouse

Apoptosis plays a key role in the physiology of multicellular organisms and is regulated by different promoting and inhibitory mechanisms. Cytokine-induced apoptotic inhibitor (CIAPI) was recently identified as a key factor involved in apoptosis inhibition in higher vertebrate lineages. However

KRAS mutant lung adenocarcinomas remain intractable for targeted therapies. Genetic interrogation of KRAS downstream effectors, including the MAPK pathway and the interphase CDKs, identified CDK4 and RAF1 as the only targets whose genetic inactivation induces therapeutic responses without causing unacceptable

D-type cyclins are central regulators of the cell division cycle and are among the most frequently deregulated therapeutic targets in human cancer1, but the mechanisms that regulate their turnover are still being debated2,3. Here, by combining biochemical and genetics studies in
