    See all Synaptophysin primary antibodies
  • Description
    Mouse monoclonal [SP15] to Synaptophysin

  • FunctionPossibly involved in structural functions as organizing other membrane components or in targeting the vesicles to the plasma membrane. Involved in the regulation of short-term and long-term synaptic plasticity.
  • Tissue specificityCharacteristic of a type of small (30-80 nm) neurosecretory vesicles, including presynaptic vesicles, but also vesicles of various neuroendocrine cells of both neuronal and epithelial phenotype.
  • Involvement in diseaseMental retardation, X-linked, SYP-related
  • Sequence similaritiesBelongs to the synaptophysin/synaptobrevin family.
    Contains 1 MARVEL domain.
  • DomainThe calcium-binding activity is thought to be localized in the cytoplasmic tail of the protein.
  • Post-translational
    Ubiquitinated; mediated by SIAH1 or SIAH2 and leading to its subsequent proteasomal degradation.
  • Cellular localizationCytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane. Cell junction, synapse, synaptosome.

Thank you for your enquiry. Synaptophysin antibodies ab11105 and ab24729 are derived from two different monoclonal clones: [SP15] and [SP17]. They were raised against different immunogens and recognise different epitopes. Both antisera have als...
