機能
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. -
配列類似性
Belongs to the GRB2/sem-5/DRK family.
Contains 1 SH2 domain.
Contains 2 SH3 domains. -
ドメイン
The SH3 domains mediate interaction with RALGPS1 and SHB. -

Predicted band size: 25 kDa
Observed band size: 26 kDa why is the actual band size different from the predicted?Anti-GRB2 antibody [Y237] (ab32037) staining at 1/5000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab32037 was shown to bind specifically to GRB2. A band was observed at 26 kDa in wild-type A431 cell lysates with a reduction in signal observed at this size in GRB2 heterozygous knockout cell line. To generate this image, wild-type and GRB2 heterozygous knockout A431 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Predicted band size: 25 kDa
Observed band size: 25 kDaLanes 1 - 4: Merged signal (red and green). Green - ab32037 observed at 25 kDa. Red - loading control, ab7291 (Mouse anti-Alpha Tubulin [DM1A]) observed at 55 kDa.
ab32037 was shown to react with GRB2 in western blot. The band observed in the CRISPR-Cas9 edited cell lysate lane above 25 kDa is likely to represent an insertion. This has not been investigated further and the functional properties of the gene product have not been determined. Cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3 % milk in TBS-T (0.1 % Tween®) before incubation with ab32037 and ab7291 (Mouse anti-Alpha Tubulin [DM1A]) overnight at 4 °C at a 1 in 5000 dilution and a 1 in 20000 dilution respectively. Blots were incubated with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 h at room temperature before imaging.
