Application examples

Application examples Western blot using anti-UmuD antibodies

Samples: Protein extract from E. coli DE274 ( lexA51, recA730) without mitomycin C treatment (1), treated with mitomycin C (2) was separated on SDS-PAGE following a transfer to a membrane. Incubation with primary antibodies at 1: 3000, followed by washes and incubation with HRP conjugated anti-rabbit IgG antibodies. Reaction was visualized by chemiluminescence according to manufacture's recommendations.

Additional information

Background

Background The products of umuD , umuC , and recA genes (SOS genes) are required for mutagenesis induced by radiation or chemical agents. Transcription of these SOS genes is repressed by a repressor, LexA protein in uninduced cells. Exposure of cells to DNA-damaging agents activates RecA protein to promote proteolytic cleavage of LexA protein. Inactivation of LexA protein by the cleavage consequently derepresses the SOS genes, umuD, C and recA . UmuD protein is then auto-cleaved, which is promoted by RecA protein ssDNA in a ATP-dependent manner. The processed UmuD protein is the active form for mutagenesis and the UmuD-UmuC complex functions as an error-prone translesion DNA polymerase.
