Gene Information

human ... RB1(5925)

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.

Biochem/physiol Actions

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.

General description

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.

Physical form

Formulated in 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20, 30% glycerol and 3 mM DTT.

Preparation Note

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.

Storage Class

10 - Combustible liquids
