Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at -20°C. Store under Desiccating conditions.

    pH: 7.40
    Constituents: PBS, 0.88% Sodium chloride

  • ReconstitutionCentrifuge the vial prior to opening. Reconstitute in sterile dH2O to a concentration of 0.1 -1mg/ml and let the lyophilized pellet dissolve completely. This solution can then be diluted into other aqueous buffers and stored at 4°C for 1 week or –20°C for future use.

  • FunctionNeurotrophic protein; induces extensive neuronal differentiation in retinoblastoma cells. Potent inhibitor of angiogenesis. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity.
  • Tissue specificityRetinal pigment epithelial cells and blood plasma.
  • Sequence similaritiesBelongs to the serpin family.
  • Developmental stageExpressed in quiescent cells.
  • DomainThe N-terminal (AA 44-121) exhibits neurite outgrowth-inducing activity. The C-terminal exposed loop (AA 382-418) is essential for serpin activity.
  • Post-translational
    modifications
    The N-terminus is blocked. Extracellular phosphorylation enhances antiangiogenic activity.
    N- and O-glycosylated. O-glycosylated with a core 1 or possibly core 8 glycan.
  • Cellular localizationSecreted. Melanosome. Enriched in stage I melanosomes.
  • Information by UniProt
