MST2 Recombinant Rabbit Monoclonal Antibody (19H19L39), Invitrogen™

Description

• This antibody is predicted to react with Monkey, Bovine, Cat
• Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems
• The expression systems are developed by cloning in the specific antibody DNA sequences from immunoreactive rabbits
• Then, individual clones are screened to select the best candidates for production
• The advantages of using recombinant rabbit monoclonal antibodies include: better specificity and sensitivity, lot-to-lot consistency, animal origin-free formulations, and broader immunoreactivity to diverse targets due to larger rabbit immune repertoire
• STK3 (MST2) is a STE kinase family member that acts upstream of the MAP kinase signaling pathways, and is known to be activated by the proapoptotic stimuli staurosporine and FAS ligand
• STK3 is a stress-activated, pro-apoptotic kinase which, following caspase-cleavage, enters the nucleus and induces chromatin condensation followed by internucleosomal DNA fragmentation
• It is a key component of the Hippo signaling pathway which plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis
• The core of this pathway is composed of a kinase cascade wherein STK3/MST2 and STK4/MST1, in complex with its regulatory protein SAV1, phosphorylates and activates LATS1/2 in complex with its regulatory protein MOB1, which in turn phosphorylates and inactivates YAP1 oncoprotein and WWTR1/TAZ
• Phosphorylation of YAP1 by LATS2 inhibits its translocation into the nucleus to regulate cellular genes important for cell proliferation, cell death, and cell migration
• STK3/MST2 and STK4/MST1 are required to repress proliferation of mature hepatocytes, to prevent activation of facultative adult liver stem cells (oval cells), and to inhibit tumor formation.
