Our Abpromise guarantee covers the use of ab133244 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/1000 - 1/10000. Predicted molecular weight: 50 kDa.|
FunctionMay play an important role in CKII- and p60c-src-induced signal transduction cascades.
Sequence similaritiesBelongs to the protein-tyrosine phosphatase family. Non-receptor class 1 subfamily.
Contains 1 tyrosine-protein phosphatase domain.
modificationsOxidized on Cys-215; the Cys-SOH formed in response to redox signaling reacts with the alpha-amido of the following residue to form a 4-amino-3-isothiazolidinone serine cross-link, triggering a conformational change that inhibits substrate binding and activity. The active site can be restored by reduction.
Cellular localizationEndoplasmic reticulum membrane.

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: PTP1B knockout HAP1 cell lysate (20 µg)
Lane 3: Jurkat cell lysate (20 µg)
Lane 4: MCF7 cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab133244 observed at 54 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab133244 was shown to recognize PTP1B when PTP1B knockout samples were used, along with additional cross-reactive bands. Wild-type and PTP1B knockout samples were subjected to SDS-PAGE. ab133244 and ab8245 (loading control to GAPDH) were diluted 1/1,000 and 1/2,000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.
