Application Abreviews Notes
ELISA 1/1000.
WB 1/100 - 1/500. Detects a band of approximately 30 kDa (predicted molecular weight: 28 kDa).
IHC-P 1/50 - 1/100.


  • FunctionAdapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways. Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif. Binding generally results in the modulation of the activity of the binding partner. Negative regulator of osteogenesis.
  • Sequence similaritiesBelongs to the 14-3-3 family.
  • Post-translational
    The alpha, brain-specific form differs from the beta form in being phosphorylated.
    Isoform Short contains a N-acetylmethionine at position 1.
  • Cellular localizationCytoplasm. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.

  • Anti-14-3-3 alpha + beta antibody (ab37550) at 1/100 dilution + Jurkat cell lysate

    Predicted band size : 28 kDa
    Observed band size : 30 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 15 kDa,70 kDa. We are unsure as to the identity of these extra bands.
  • Formalin-fixed and paraffin-embedded human breast cancer tissue stained with ab37550 at a 1/50 dilution (a peroxidase-conjugated secondary antibody was used, followed by AEC staining).

    This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.
