Target

  • Function

    Coreceptor for SEMA3A. Necessary for signaling by class 3 semaphorins and subsequent remodeling of the cytoskeleton. Plays a role in axon guidance, invasive growth and cell migration. Class 3 semaphorins bind to a complex composed of a neuropilin and a plexin. The plexin modulates the affinity of the complex for specific semaphorins, and its cytoplasmic domain is required for the activation of down-stream signaling events in the cytoplasm.
  • Tissue specificity

    Detected in fetal brain.
  • Sequence similarities

    Belongs to the plexin family.
    Contains 4 IPT/TIG domains.
    Contains 1 Sema domain.
  • Cellular localization

    Membrane.

Images

  • IHC-FoFr image of Plexin A2 staining on mouse cortex (Lamina V) using ab39357 (1/300). The sections used came from animals perfused fixed with Paraformaldehyde 4% with 15% of a solution of saturated picric acid, in phosphate buffer 0.1M. Following postfixation in the same fixative overnight, the brains were cryoprotected in sucrose 30% overnight. Brains were then cut using a cryostat and the immunostainings were performed using the ‘free floating’ technique.

    Secondary
    Goat Polyclonal to rabbit IgG - H&L - Pre adsorbed (HRP) at 1/3000 dilution

    Performed under reducing conditions.

    Predicted band size: 212 kDa
    Observed band size: 230 kDa
    why is the actual band size different from the predicted?



    Plexin A2 contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.

  • Immunofluorescence analysis of mouse neural tube cells, staining Plexin A2 (green) with ab39357.

    Cells were fixed before being blocked with 10% serum for 1 hour at 26°C. Samples were incubated with primary antibody (1/100 in diluent) for 12 hours at 4°C. An AlexaFluor®488-conjugated goat anti-rabbit polyclonal IgG (1/500) was used as the secondary antibody.
