Recombinant Human Pirin

Pirin, Probable quercetin 2,3-dioxygenase PIR, Probable quercetinase, PIR.

Pirin (PIR) which belongs to the cupin superfamily, is an Fe(II)-containing nuclear protein expressed in all tissues of the body and concentrated within dot-like subnuclear structures. Pirin may function as a transcriptional cofactor and is involved in the regulation of DNA transcription and replication, as a result of interactions with nuclear factor I/CCAAT box transcription factor as well as B cell lymphoma 3-encoded oncoprotein.

PIR Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 310 amino acids (1-290 a.a.) and having a molecular mass of 34.3kDa.
PIR is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Escherichia Coli.

Sterile Filtered clear solution.
