Scientific Data

Western Blot Detection of Human/Mouse/Rat PP2C beta /PPM1B antibody by Western Blot. View Larger

Detection of Human/Mouse/Rat PP2C beta /PPM1B by Western Blot. Western blot shows lysates of CHP-100 human neuroblastoma cell line and A20 mouse B cell lymphoma cell line. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat PP2C beta /PPM1B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4396) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). Specific bands were detected for PP2C beta/PPM1B at approximately 53 and 36 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 1.

Background: PP2C beta/PPM1B

Protein phosphatase 2C beta (PP2C beta ), also called protein phosphatase, magnesium-dependent type 1B (PPM1B), preferentially dephosphorylates serine and threonine residues on proteins. There are five splice variants with sizes of 53, 43, 42, 36, and 21 kDa. This enzyme is resistant to inhibitors of other protein phosphatases such as okadaic acid and calyculin. Association of PP2C beta with I kappa B kinase inhibits its phosphorylating activity and is regulated by TNFalpha stimulation. PP2C beta is found in many cell types and tissues, especially muscle. The mRNA for PP2C beta accumulates in mature spermatocytes and metaphase-arrested, unfertilized oocytes. Knockout of PP2C beta in mice is lethal prior to embryo implantation.
