  • 产品描述：

    The LexA antibody is prepared through the immunization of rabbits with the peptide corresponding to amino acids 1-202 of the recombinant E.coli LexA repressor protein and further purification from rabbit antiserum by protein G. It is a polyclonal antibody and exists as an unconjugated IgG. Its purity reaches up to 95%. It only reacts with the LexA protein of E.coli-origin. And this anti-LexA antibody has been validated for use in ELISA and WB analyses. In E.coli, the transcriptional repressor LexA controls the SOS response, which is a coordinated cellular response to DNA damage. The LexA protein inhibits gene expression by binding as a dimer to a 16-mer consensus sequence CTG-N10-CAG named SOS boxes.

  • 功能：
    Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. Binds to the 16 bp palindromic sequence 5'-CTGTATATATATACAG-3'. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair. Implicated in hydroxy radical-mediated cell death induced by hydroxyurea treatment.The SOS response controls an apoptotic-like death (ALD) induced (in the absence of the mazE-mazF toxin-antitoxin module) in response to DNA damaging agents that is mediated by RecA and LexA.
