The invention discloses a
peroxiredoxin 1
binding protein and application thereof, and the
peroxiredoxin 1
binding protein comprises one or more of TXN (Trx), ASK1, TPM3, CFL1, GTPBP4, DIRAS2 and PPP2R1A. By
immunoprecipitation assay, the
peroxiredoxin 1
binding protein can be bonded to peroxiredoxin 1, and
nicotine can promote the binding of the peroxiredoxin 1 and the peroxiredoxin 1 binding
protein. In oral precancerous lesions such as
leukoplakia cells, the expression of the peroxiredoxin 1 binding
protein is significantly increased, and the
nicotine can regulate the expression of the theperoxiredoxin 1 binding
protein. The peroxiredoxin 1 binding protein can be used as a
molecular marker for diagnosing or preventing the oral precancerous lesions such as oral
leukoplakia, preparing aPrx1 protein conjugate, or binding, labeling, identifying, enriching, sorting or purifying Prx1 overexpresses cells.
