Anti-RB1 (Ab-807) antibody produced in rabbit

MFCD00282455

NA.41

The gene encoding Retinoblastoma-associated protein (RB1) is a tumor suppressor gene localized on human chromosome 13q14.2.

Peptide sequence around aa. 805-809 (Y-I-S-P-L), according to the protein RB1.

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.

Rb operates in the midst of the cell cycle clock apparatus. Its main role is to act as a signal transducer connecting the cell cycle clock with the transcriptional machinery (Ref.1). It plays an important role in the Rb/ E2F pathway in cell proliferation, cell fate determination, and cancer (Ref.2). Cellular senescence is a stable form of cell cycle arrest that limits proliferation of damaged cells and act as a natural barrier to cancer progression. A distinct heterochromatic structure that accumulates in senescent human fibroblasts, designated as SAHF (Senescence-Associated Heterochromatic Foci). SAHF formation coincides with recruitment of heterochromatin proteins and the Rb protein to E2F-responsive promoters and is associated with the stable repression of E2F target genes. Both SAHF formation and the silencing of E2F target genes depended on the integrity of the Rb pathway and do not occur in reversibly arrested cells (Ref.3). Rb activates transcription of the c-Jun gene through the SP1-binding site within the c-Jun promoter.
