General description

Monoclonal Anti-RAP1 (mouse IgG2b isotype) is derived from the hybridoma 4C8/1 produced by the fusion of mouse myeloma cells (Sp2/0 Ag.14 cells) and splenocytes from BALB/c mice immunized with human RAP1. Ras-related protein 1 (RAP1) protein contains 399 amino acids with an acidic C-terminus featuring a 33 amino acid coiled-coil region and a bipartite nuclear localization signal. It is expressed ubiquitously, is located at telomeres and affects telomer length.
Rap1 (repressor/activator protein) is a constituent of shelterin. It consists of an N-terminal BRCT motif, a C-terminal protein interaction domain, and one or two central Myb domains. It is also known as Terf2ip (TERF2 interacting protein). It is located on chromosome 16q23.1.

Immunogen

human RAP1.

Application

Monoclonal Anti-RAP1 antibody produced in mouse may be used in enzyme linked immunosorbent assay (ELISA) and immunoblotting.

Biochem/physiol Actions

Rap1 (repressor/activator protein) helps to guard telomeres, assemble telomerase, and controls telomere length. At telomeres, Rap1 also participates in the suppression of non-homologous end joining (NHEJ). It involves in genomewide transcriptional modulation. Knockdown of Rap1 induces apoptosis in hepatocellular carcinoma cell line HepG2.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
