Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 75 kDa (predicted molecular weight: 60 kDa).
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ICC/IF 1/100 - 1/250.
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function
      Transcriptional coactivator involved in neuroepithelial stem cell differentiation and neurogenesis. Involved in particular in lens epithelial cell gene regulation and stress responses. May play an important role in lens epithelial to fiber cell terminal differentiation. May play a protective role during stress-induced apoptosis. Isoform 2 is a more general and stronger transcriptional coactivator. Isoform 2 may also act as an adapter to coordinate pre-mRNA splicing. Cellular cofactor for lentiviral integration.
    • Tissue specificity
      Widely expressed. Expressed at high level in the thymus. Expressed in fetal and adult brain. Expressed in neurons, but not astrocytes. Markedly elevated in fetal as compared to adult brain. In the adult brain, expressed in the subventricular zone (SVZ), in hippocampus, and undetectable elsewhere. In the fetal brain, expressed in the germinal neuroepithelium and cortical plate regions.
    • Involvement in disease
      Note=A chromosomal aberration involving PSIP1 is associated with pediatric acute myeloid leukemia (AML) with intermediate characteristics between M2-M3 French-American-British (FAB) subtypes. Translocation t(9;11)(p22;p15) with NUP98. The chimeric transcript is an in-frame fusion of NUP98 exon 8 to PSIP1/LEDGF exon 4.
    • Sequence similarities
      Belongs to the HDGF family.
      Contains 1 PWWP domain.
    • Domain
      Residues 340-417 are necessary and sufficient for the interaction with HIV-1 IN (IBD domain).
    • Post-translational
      Phosphorylated upon DNA damage, probably by ATM or ATR.
    • Cellular localization
      Nucleus. Remains chromatin-associated throughout the cell cycle.
