Application Abreviews Notes
WB Use a concentration of 1 mg/ml. Detects a band of approximately 80 kDa (predicted molecular weight: 73 kDa).


  • Function

    Binds to the dendritic targeting element and may play a role in mRNA trafficking (By similarity). Part of a ternary complex that binds to the downstream control sequence (DCS) of the pre-mRNA. Mediates exon inclusion in transcripts that are subject to tissue-specific alternative splicing. May interact with single-stranded DNA from the far-upstream element (FUSE). May activate gene expression. Also involved in degradation of inherently unstable mRNAs that contain AU-rich elements (AREs) in their 3'-UTR, possibly by recruiting degradation machinery to ARE-containing mRNAs.
  • Tissue specificity

    Detected in neural and non-neural cell lines.
  • Sequence similarities

    Belongs to the KHSRP family.
    Contains 4 KH domains.
  • Post-translational

    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localization

    Nucleus. Cytoplasm. A small proportion is also found in the cytoplasm of neuronal cell bodies and dendrites.

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 73 kDa
    Observed band size: 88 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 30 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 16 minutes

    Abcam recommends using milk as the blocking agent and we expect this antibody to react with KHSRP at approximately 88 kDa. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
