Post Translational Modifications: Phosphorylated by CK2 and this positively regulates its activity. Sumoylation represses the transcriptional activity and displays enhanced resistance to protein degradation. Inactivates the tumor suppressor activity. Elevated levels in tumor cells. Major site is Lys-275. Sumoylation is enhanced by PIAS3 (By similarity). Desumoylated by SENP1 in tumor cells and appears to compete with ubiquitination on C-terminal sites. Ubiquitinated. Appears to compete with sumoylation on C-terminal sites.
Subunit Structure: Monomer. Homodimer. Interacts with MYD88 and PIAS3 (By similarity). Interacts with EP300.
Similarity: Belongs to the IRF family.

NCBI Description
The protein encoded by this gene is a transcriptional regulator and tumor suppressor, serving as an activator of genes involved in both innate and acquired immune responses. The encoded protein activates the transcription of genes involved in the body's response to viruses and bacteria, playing a role in cell proliferation, apoptosis, the immune response, and DNA damage response. This protein represses the transcription of several other genes. As a tumor suppressor, it both suppresses tumor cell growth and stimulates an immune response against tumor cells. Defects in this gene have been associated with gastric cancer, myelogenous leukemia, and lung cancer. [provided by RefSeq, Aug 2017]
Uniprot Description
IRF1: a transcriptional regulator which displays a remarkable functional diversity in the regulation of cellular responses. These include the regulation of IFN and IFN-inducible genes, host response to viral and bacterial infections, regulation of many genes expressed during hematopoiesis, inflammation, immune responses and cell proliferation and differentiation, regulation of the cell cycle and induction of growth arrest and programmed cell death following DNA damage. Stimulates both innate and acquired immune responses through the activation of specific target genes and can act as a transcriptional activator and repressor regulating target genes by binding to an interferon- stimulated response element (ISRE) in their promoters. Its target genes for transcriptional activation activity include: genes involved in anti-viral response, such as IFN-alpha/beta, DDX58, TRAIL, OAS1/2, PIAS1, PKR and RSAD2; antibacterial response, such as iNOS; anti- proliferative response, such as p53, LOX and CDKN1A; apoptosis, such as PUMA, CASP1, CASP7 and CASP8; immune response, such as IL7, IL12A/B and IL15, COX-2 and CYBB; DNA damage responses and DNA repair, such as POLQ; MHC class I expression, such as TAP1, PSMB9, PSME1, PSME2 and B2M and MHC class II expression, such as CIITA. Represses genes involved in anti-proliferative response, such as survivin, CCNB1, CCNE1, CDK1, CDK2 and CDK4 and in immune response, such as FOXP3, IL4, ANXA2 and TLR4. Stimulates p53-dependent transcription through enhanced recruitment of EP300 leading to increased acetylation of p53. Plays an important role in immune response directly affecting NK maturation and activity, macrophage production of IL12, Th1 development and maturation of CD8+ T-cells. Also implicated in the differentiation and maturation of dendritic cells and in the suppression of regulatory T (Treg) cells development. Acts as a tumor suppressor and plays a role not only in antagonism of tumor cell growth but also in stimulating an immune response against tumor cells. Defects in IRF1 are a cause of gastric adenocarcinoma (GASC), accounting for most of all gastric malignant tumors. Deletions or rearrangements of IRF1 can occur in preleukemic myelodysplastic syndrome (MDS) and acute myelogenous leukemia (AML).

Product Notes
The IRF1 irf1 (Catalog #AAA9611397) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The IRF1 Antibody reacts with Human, Mouse, Rat Predicted: Pig, Bovine, Horse, Sheep, Rabbit, Dog and may cross-react with other species as described in the data sheet. AAA Biotech's IRF1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). WB: 1:500-1:2000. Researchers should empirically determine the suitability of the IRF1 irf1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "IRF1, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
