General description

Monoclonal Anti-Mus81 (mouse IgG2a isotype) is derived from the hybridoma MTA30 2G10/3 produced by the fusion of mouse myeloma cells (Sp2/0 Ag.14 cells) and splenocytes from BALB/c mice immunized with Mus81 protein. Crossover junction endonuclease Mus81 protein was identified by screening a human cerebellum cDNA library with a probe from the yeast Mus81. The human Mus81 has 551 amino acids with a molecular mass of 59 kDa. The highest sequence similarity between different species is around the VERKX3D motif. This motif is conserved in the endonuclease family (XPF) family of nucleases. The protein has helix-hairpin-helix DNA-binding domains in the N- and C-termini of the protein that are also conserved.

Immunogen

Mus81 protein.

Application

Anti-Mus81 antibody, Mouse monoclonal has been used in immunofluorescence, immunoblotting and immunoprecipitation.

Biochem/physiol Actions

Crossover junction endonuclease Mus81 is elevated in cells exposed to agents that block DNA replication. Knockout mice that are homozygous Mus81-/-, or their heterozygous cohorts Mus81-/+, are susceptible to spontaneous chromosomal damage and cancer predisposition suggesting that this protein is important for genomic integrity and tumor suppression

Physical form

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

Interstrand cross-link (ICL) hypersensitivity is a characteristic trait of Fanconi anemia (FA). Although FANCD2-associated nuclease 1 (FAN1) contributes to ICL repair, FAN1 mutations predispose to karyomegalic interstitial nephritis (KIN) and cancer rather than to FA. Thus, the biological role of
