|Application ||WB, E|
|Other Accession||NP_003653, 8544|
|Calculated MW||32113 Da|
|Other Names||Pirin, 22.214.171.124, Probable quercetin 2, 3-dioxygenase PIR, Probable quercetinase, PIR|
|Format||0.5 mg IgG/ml in Tris saline (20mM Tris pH7.3, 150mM NaCl), 0.02% sodium azide, with 0.5% bovine serum albumin|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Goat Anti-Pirin Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Transcriptional coregulator of NF-kappa-B which facilitates binding of NF-kappa-B proteins to target kappa-B genes in a redox-state-dependent manner. May be required for efficient terminal myeloid maturation of hematopoietic cells. Has quercetin 2,3-dioxygenase activity (in vitro).|
|Cellular Location||Nucleus. Cytoplasm. Note=Predominantly localized in dot-like subnuclear structures. Cytoplasmic localization of PIR seems to positively correlate with melanoma progression|
|Tissue Location||Highly expressed in a subset of melanomas. Detected at very low levels in most tissues (at protein level) Expressed in all tissues, with highest level of expression in heart and liver.|

This gene encodes a member of the cupin superfamily. The encoded protein is an Fe(II)-containing nuclear protein expressed in all tissues of the body and concentrated within dot-like subnuclear structures. Interactions with nuclear factor I/CCAAT box transcription factor as well as B cell lymphoma 3-encoded oncoprotein suggest the encoded protein may act as a transcriptional cofactor and be involved in the regulation of DNA transcription and replication. Alternatively spliced transcript variants have been described.
