  • Function
    Adapter protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway.
    Isoform GRB3-3 does not bind to phosphorylated epidermal growth factor receptor (EGFR) but inhibits EGF-induced transactivation of a RAS-responsive element. Isoform GRB3-3 acts as a dominant negative protein over GRB2 and by suppressing proliferative signals, may trigger active programmed cell death.
  • Sequence similarities
    Belongs to the GRB2/sem-5/DRK family.
    Contains 1 SH2 domain.
    Contains 2 SH3 domains.
  • Domain
    The SH3 domains mediate interaction with RALGPS1 and SHB.
  • Cellular localization
    Golgi apparatus.

Customer reviews and Q&As


Thank you for contacting us.

The following standard heat-mediated citrate buffer antigen retrieval was used for the IHC validation of ab32111 and ab111031. Antibody ab111586 used citrate buffer in a pressure cooker at 120C for 5 minutes but a steamer or waterbath at 95-100C will be an acceptable substitute.

Place slides in a container of 0.01 M sodium citrate buffer, pH 6.0 heated to 100°C and maintain this temperature for 20 minutes by placing the container in a steamer or heated waterbath. After 20 minutes, remove from heat and let stand at room temperature in buffer for 20 minutes. Rinse in 1X TBS with Tween (TBST) for 1 minute at RT.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
