  • Target

    • Function
      Proteoglycan playing a role in cell proliferation and migration which stimulates endothelial cells motility during microvascular morphogenesis. May also inhibit neurite outgrowth and growth cone collapse during axon regeneration. Cell surface receptor for collagen alpha 2(VI) which may confer cells ability to migrate on that substrate. Binds through its extracellular N-terminus growth factors, extracellular matrix proteases modulating their activity. May regulate MPP16-dependent degradation and invasion of type I collagen participating in melanoma cells invasion properties. May modulate the plasminogen system by enhancing plasminogen activation and inhibiting angiostatin. Functions also as a signal transducing protein by binding through its cytoplasmic C-terminus scaffolding and signaling proteins. May promote retraction fiber formation and cell polarization through Rho GTPase activation. May stimulate alpha-4, beta-1 integrin-mediated adhesion and spreading by recruiting and activating a signaling cascade through CDC42, ACK1 and BCAR1. May activate FAK and ERK1/ERK2 signaling cascades.
    • Tissue specificity
      Detected only in malignant melanoma cells.
    • Sequence similarities
      Contains 15 CSPG (NG2) repeats.
      Contains 2 laminin G-like domains.
    • Post-translational
      O-glycosylated; contains glycosaminoglycan chondroitin sulfate which are required for proper localization and function in stress fiber formation (By similarity). Involved in interaction with MMP16 and ITGA4.
      Phosphorylation by PRKCA regulates its subcellular location and function in cell motility.
    • Cellular localization
      Apical cell membrane. Cell projection > lamellipodium membrane. Localized at the apical plasma membrane it relocalizes to the lamellipodia of astrocytoma upon phosphorylation by PRKCA. Localizes to the retraction fibers. Localizes to the plasma membrane of oligodendrocytes.

    Thank you for your inquiry.

    Indeed, you are right. The three antibodies, ab78284, ab83508 and ab20156, are the only antibodies against NG2 which have been tested in flow cytometry and on human cells. Of those three, the ab20156 is the only on...

    Merci de nous avoir contactés.

    Nous n'avons malheureusement pas d'anticorps anti-NG2 conjugué à un fluorochrome. Nous avons par contre des kits de conjugaison simples et rapides à utiliser permettant le couplage d'...
