    羊多克隆抗体to SQSTM1 / p62
  • 特异性
    ab31545 recognises SQSTM1/p62 in normal and diseased human brain.
  • 经测试应用
    适用于: IHC-P, IHC-Fr, WBmore details
  • 种属反应性
    与反应: Human
  • 免疫原

    Synthetic peptide from part of human Ubiquitin Interactive Motif (UIM) derived from p62 protein, also known as SQSTM1. Amino acid sequence: PPEADPRLIE SLSQMLSMGF SDEGGWLTRL LQTKNYDIGA

  • 阳性对照
    • Human brain homogenate
  • 常规说明

    In western blot the antibody recognizes 4 major bands of 130, 62, 45 and 22 kDa in human brain homogenate. The antibody may also recognize some proteins containing SQSTM1 domains from other species as 80, 62 and 47 kDa proteins are identified in rat sympathetic ganglia. Preincubation of the antibody with the immunizing peptide abolishes all reactivity in both human brain homogenate and rat sympathitic ganglia.



Our Abpromise guarantee covers the use of ab31545 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
IHC-P Use at an assay dependent dilution.
IHC-Fr 1/500 - 1/2000.
WB Use at an assay dependent dilution. Detects a band of approximately 47, 50 kDa (predicted molecular weight: 47 kDa).


  • 功能
    Adapter protein which binds ubiquitin and may regulate the activation of NFKB1 by TNF-alpha, nerve growth factor (NGF) and interleukin-1. May play a role in titin/TTN downstream signaling in muscle cells. May regulate signaling cascades through ubiquitination. Adapter that mediates the interaction between TRAF6 and CYLD (By similarity). May be involved in cell differentiation, apoptosis, immune response and regulation of K(+) channels.
  • 组织特异性
    Ubiquitously expressed.
  • 疾病相关
    Defects in SQSTM1 are a cause of Paget disease of bone (PDB) [MIM:602080]. PDB is a metabolic bone disease affecting the axial skeleton and characterized by focal areas of increased and disorganized bone turn-over due to activated osteoclasts. Manifestations of the disease include bone pain, deformity, pathological fractures, deafness, neurological complications and increased risk of osteosarcoma. PDB is a chronic disease affecting 2 to 3% of the population above the age of 40 years.
  • 序列相似性
    Contains 1 OPR domain.
    Contains 1 UBA domain.
    Contains 1 ZZ-type zinc finger.
  • 结构域
    The UBA domain binds specifically 'Lys-63'-linked polyubiquitin chains of polyubiquitinated substrates. Mediates the interaction with TRIM55.
    The OPR domain mediates homooligomerization and interactions with PRKCZ, PRKCI, MAP2K5 and NBR1.
    The ZZ-type zinc finger mediates the interaction with RIPK1.
  • 翻译后修饰
    Phosphorylated. May be phosphorylated by PRKCZ (By similarity). Phosphorylated in vitro by TTN.
  • 细胞定位
    Cytoplasm. Late endosome. Nucleus. Sarcomere (By similarity). In cardiac muscles localizes to the sarcomeric band (By similarity). Localizes to late endosomes. May also localize to the nucleus. Accumulates in neurofibrillary tangles and in Lewy bodies of neurons from individuals with Alzheimer and Parkinson disease respectively. Enriched in Rosenthal fibers of pilocytic astrocytoma. In liver cells, accumulates in Mallory bodies associated with alcoholic hepatitis, Wilson disease, indian childhood cirrhosis and in hyaline bodies associated with hepatocellular carcinoma.

  • ab31545 staining SQSTM1 / p62 in murine spinal cord sections by Immunohistochemistry (Frozen sections).
    Tissue was fixed in 4% paraformaldehyde, blocked with 10% goat serum for 2 hours at 25°C and then incubated with ab31545 at a 1/500 dilution for 18 hours at 4°C. The secondary used was an Alexa-Fluor 594 conjugated donkey anti-sheep (H+L) polyclonal used at a 1/1000 dilution.
