ANTI-MUS81 ANTIBODY, MOUSE MONOCLONAL

The Uses of ANTI-MUS81 ANTIBODY, MOUSE MONOCLONAL

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

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.

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
