应用 Ab评论 说明
WB 1/1000 - 1/10000. Predicted molecular weight: 72 kDa.
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval via the pressure cooker method before commencing with IHC staining protocol. Heat up to 98 degrees C, below boiling, and then let cool for 10-20 min.
ICC 1/100 - 1/250.
Flow Cyt 1/100 - 1/500. ab172730-Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
  • 应用说明Is unsuitable for IP.
  • 靶标

    • 功能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.
    • 组织特异性Expressed in numerous tissues with highest level in testis.
    • 通路Protein modification; protein sumoylation.
    • 序列相似性Belongs to the PIAS family.
      Contains 1 PINIT domain.
      Contains 1 SAP domain.
      Contains 1 SP-RING-type zinc finger.
    • 结构域The LXXLL motif is a transcriptional coregulator signature.
      The SP-RING-type domain is required for promoting EKLF sumoylation.
    • 翻译后修饰Sumoylated.
      Dimethylated by PRMT1 at Arg-303 in the late phase of interferon gamma (IFN-gamma) signaling, leading to preferential interaction with STAT1 and thus resulting in release of STAT1 from its target gene.
    • 细胞定位Nucleus speckle. Interaction with CSRP2 may induce a partial redistribution along the cytoskeleton.
