Immunocytochemistry/ Immunofluorescence analysis of HeLa (human cervix adenocarcinoma epithelial cell) cells labeling PIAS1 with purified ab109388 at 1/500 dilution (4.6 μg/mL). Cells were fixed in 100% Methanol. Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) was used as the secondary antibody at 1/1000 (2 μg/mL) dilution. DAPI (blue) was used as nuclear counterstain.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab109388).

We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

PIAS1 also known as Protein Inhibitor of Activated STAT 1 functions as a E3 SUMO-protein ligase which regulates protein function and localization through sumoylation. It has a molecular mass of approximately 70 kDa. PIAS1 is widely expressed in a variety of tissues indicating its involvement in diverse cellular functions. This protein binds to target proteins and modulates their activity impacting how cells respond to different stimuli.
Biological function summary

PIAS1 influences transcription regulation and gene expression. It acts as a transcriptional co-regulator by interacting with various transcription factors and modulating their activity. PIAS1 is part of multiprotein complexes that mediate these regulatory processes. Its activity is important for maintaining a balanced gene expression which if uncontrolled may result in abnormal cell behavior.

Pathways

PIAS1 plays an important role in signal transduction pathways such as the JAK/STAT pathway and the NF-kB signaling pathway. It interacts with proteins like STAT an important component in these pathways to regulate immune responses and cell growth. PIAS1 modulates the activity of these pathways in part by the covalent attachment of the small ubiquitin-like modifier (SUMO) proteins demonstrating its importance in cellular signaling networks.

PIAS1 relates closely to cancer progression and autoimmune diseases. Abnormal PIAS1 function or expression has links to certain cancers due to its role in controlling cell proliferation and differentiation. In autoimmune disorders PIAS1 affects immune regulation through its interaction with Signal Transducer and Activator of Transcription proteins showing altered activity in diseases like rheumatoid arthritis. Understanding PIAS1's contributions to these pathological states helps in developing targeted therapies.

Target data

Functions as an E3-type small ubiquitin-like modifier (SUMO) ligase, stabilizing the interaction between UBE2I and the substrate, and as a SUMO-tethering factor (PubMed : 11583632, PubMed : 11867732, PubMed : 14500712, PubMed : 15280358, PubMed : 21965678, PubMed : 36050397). Catalyzes sumoylation of various proteins, such as CEBPB, MRE11, MTA1, PTK2, PML and ZNF76 (PubMed : 11583632, PubMed : 11867732, PubMed : 14500712, PubMed : 15280358, PubMed : 21965678, PubMed : 36050397). Plays a crucial role as a transcriptional coregulation in various cellular pathways, including the STAT pathway, the p53 pathway and the steroid hormone signaling pathway (PubMed : 11583632, PubMed : 11867732). In vitro, binds A/T-rich DNA (PubMed : 15133049). The effects of this transcriptional coregulation, transactivation or silencing, may vary depending upon the biological context (PubMed : 11583632, PubMed : 11867732, PubMed : 14500712, PubMed : 21965678, PubMed : 36050397). Mediates sumoylation of MRE11, stabilizing MRE11 on chromatin during end resection (PubMed : 36050397). Sumoylates PML (at 'Lys-65' and 'Lys-160') and PML-RAR and promotes their ubiquitin-mediated degradation (By similarity). PIAS1-mediated sumoylation of PML promotes its interaction with CSNK2A1/CK2 which in turn promotes PML phosphorylation and degradation (By similarity). Enhances the sumoylation of MTA1 and may participate in its paralog-selective sumoylation (PubMed : 21965678). Plays a dynamic role in adipogenesis by promoting the SUMOylation and degradation of CEBPB (By similarity). Mediates the nuclear mobility and localization of MSX1 to the nuclear periphery, whereby MSX1 is brought into the proximity of target myoblast differentiation factor genes (By similarity). Also required for the binding of MSX1 to the core enhancer region in target gene promoter regions, independent of its sumoylation activity (By similarity). Capable of binding to the core enhancer region TAAT box in the MYOD1 gene promoter (By similarity).. (Microbial infection) Restricts Epstein-Barr virus (EBV) lytic replication by acting as an inhibitor for transcription factors involved in lytic gene expression (PubMed : 29262325). The virus can use apoptotic caspases to antagonize PIAS1-mediated restriction and express its lytic genes (PubMed : 29262325).
