  • Function

    Stress-activated, pro-apoptotic kinase which, following caspase-cleavage, enters the nucleus and induces chromatin condensation followed by internucleosomal DNA fragmentation. 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 MST1/MST2, 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. MST1/MST2 are required to repress proliferation of mature hepatocytes, to prevent activation of facultative adult liver stem cells (oval cells), and to inhibit tumor formation (By similarity). Phosphorylates 'Ser-14' of histone H2B (H2BS14ph) during apoptosis. Phosphorylates FOXO3 upon oxidative stress, which results in its nuclear translocation and cell death initiation.

    Question

    Inquiry: I would like to ask you for complete sequence of the recombinant MST1 protein. Then I would like to known if your protein is already phosphorylated on serine and threonine residues and if yes, do you know numbers of phosphorylated residues? Thanks in advance.

    Asked on Oct 18 2012

    Answer

    Thank you for your enquiry.

    I can confirm that ab60337 MST1 protein (Active) has been phosphorylated. However, we have not done any in-house characterization studies to assess the state of activation/phosphorylation on specific sites. We have performed the radiometric assay to show that the kinase is indeed active.

    To manage the customers expectations, specific protein and immunogen sequences are sometimes confidential. I would appreciate if you are able to let me know why they require this sequence?

    I hope this will be helpful. Please do not hesitate to contact me again if you require further information.

    Answer

    Thank you for your inquiry.
    Please find the attached for the full sequence information for ab60337.
    As far as the kinase is concerned, we do know of various sites are phosphorylated. However, we have not done any in-house characterization studies to analyse what sites specifically are phosphorylated and to what state.
    This page gives an overview about all possible phosphosites:
