Biological background

PIAS1 (protein: Lysosome-associated membrane glycoprotein 2 (Lamp2)) is a commonly studied target in molecular and cellular biology. Functional context (as provided): 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. 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. In vitro, binds A/T-rich DNA. The effects of this transcriptional coregulation, transactivation or silencing, may vary depending upon the biological context. Together with PRMT1, may repress STAT1 transcriptional activity, in the late phase of interferon gamma (IFN-gamma) signaling. Sumoylates PML (at'Lys-65' and 'Lys-160') and PML-RAR and promotes their ubiquitin-mediated degradation. 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. Plays a dynamic role in adipogenesis by promoting the SUMOylation and degradation of CEBPB (By similarity). . Reported cellular localization context: Nucleus speckle . Nucleus, PML body . Interaction with CSRP2 may induce a partial redistribution along the cytoskeleton. Tissue expression notes (as provided): Expressed in numerous tissues with highest level in testis. .

Research relevance and current trends

• Research context keywords from the source record include: 2339,Co-Activators/Co-Repressors,Epigenetics and Nuclear Signaling,Nuclear Receptors,Nuclear Signaling Pathways,Transcription,Ubiquitin & Ubiquitin Like Modifiers.
• Current studies often focus on connecting target abundance/localization to pathway perturbations across models, tissues, and cell states.
• Quantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.

Common research applications

• Western blotting (WB): assess relative target abundance across samples, treatments, or time-points.
• Immunohistochemistry (IHC): evaluate spatial distribution of target-positive staining in tissue architecture.
• Immunofluorescence/ICC (IF/ICC): visualize subcellular localization patterns and cell-to-cell heterogeneity.
• Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.

Workflow ideas (metafield): Validate PIAS1 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect PIAS1 expression by Western blot in cell or tissue lysates, Detect PIAS1 in FFPE tissue sections by immunohistochemistry, Localize PIAS1 by immunofluorescence/immunocytochemistry in cultured cells, Quantify PIAS1-positive cells by flow cytometry in single-cell suspensions

Notes for experimental interpretation

• Consider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.
• Apparent molecular weight may vary by sample type and processing (observed MW: 72 kDa; calculated MW: 71836 MW).
• Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
