Application Abreviews Notes
WB 1/20000 - 1/100000. Detects a band of approximately 68 kDa (predicted molecular weight: 49 kDa).
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval via the pressure cooker method before commencing with IHC staining protocol.
ICC/IF 1/100 - 1/250.
  • Application notesIs unsuitable for Flow Cyt or IP.
  • Target

    • FunctionRecruited and tyrosine phosphorylated by several receptor systems, for example the T-cell, leptin and insulin receptors. Once phosphorylated, functions as an adapter protein in signal transduction cascades by binding to SH2 and SH3 domain-containing proteins. Role in G2-M progression in the cell cycle. Represses CBP-dependent transcriptional activation apparently by competing with other nuclear factors for binding to CBP. Also acts as a putative regulator of mRNA stability and/or translation rates and mediates mRNA nuclear export.
      Isoform 3, which is expressed in growth-arrested cells only, inhibits S phase.
    • Tissue specificityUbiquitously expressed in all tissue examined. Isoform 1 is expressed at lower levels in brain, skeletal muscle, and liver whereas isoform 3 is intensified in skeletal muscle and in liver.
    • Sequence similaritiesBelongs to the KHDRBS family.
      Contains 1 KH domain.
    • Developmental stageIsoform 3 is only expressed in growth-arrested cells.
    • DomainThe KH domain is required for binding to RNA.
      The Pro-rich domains are flanked by Arg/Gly-rich motifs which can be asymmetric dimethylated on arginine residues to give the DMA/Gly-rich regions. Selective methylation on these motifs can modulate protein-protein interactions.
    • Post-translational
      Tyrosine phosphorylated by several non-receptor tyrosine kinases, for example LCK, FYN and JAK3. Negatively correlates with ability to bind RNA but required for many interactions with proteins.
      Acetylated. Positively correlates with ability to bind RNA.
      Arginine methylation is required for nuclear localization. Also can affect interaction with other proteins. Inhibits interaction with Src-like SH3 domains, but not interaction with WW domains of WBP4/FBP21 AND FNBP4/FBP30.
      Arg-291, Arg-331 and Arg-346 are found to be also dimethylated, probably to asymmetric dimethylarginine.
