Overlay histogram showing HeLa cells stained with ab203967 (red line). The cells were fixed with 4% formaldehyde (10 min) and then permeabilized with 90% methanol at -20°C for 15 min. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab203967, 1/50 dilution) for 30 min at 22°C.

Isotype control antibody (black line) was rabbit IgG (monoclonal) Alexa Fluor® 594 (ab208568) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

Acquisition of >5,000 events were collected using a 50 mW Yellow/Green laser (561nm) and 610/20 bandpass filter.

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).
