REACH authorisation
Abcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.
It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.
Lysate preparation:
Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10).
This means that the protein of interest is denatured.
If you require a native form of the protein please use the live cell version. Please refer to our lysis protocol for further details on how our lysates are prepared.

Serine/threonine-protein kinase 4 (MST-1) also known as STK4 is a 52 kDa enzyme that plays an important role in cellular signaling processes. This kinase ubiquitously expresses in many tissues including liver kidney and heart. MST-1 functions as a part of a complex facilitating its catalytic activity by activating downstream substrates. The alternative name for this protein is mammalian STE20-like protein kinase 1 linking MST-1 to a family of serine/threonine kinases.
Biological function summary
This kinase orchestrates various cellular processes mainly through regulation of apoptosis and cell stress responses. MST-1 interacts with other signaling molecules in cells forming part of larger multi-protein complexes. These interactions allow MST-1 to act as a molecular switch effectively controlling the balance between cell survival and death. The cellular localization and interaction partners help diversify its biological roles.
Pathways
MST-1 predominantly influences the Hippo signaling pathway—a pathway significant in controlling organ size and suppressing cancer. In this pathway MST-1 phosphorylates and activates LATS1/2 kinases creating an endpoint effect on cell proliferation and apoptosis. MST-1 also participates in the oxidative stress response pathway where it shows interaction with FoxO transcription factors leading to modifications in gene expression profiles.
The dysregulation of MST-1 is linked to cancer and cardiovascular diseases. In cancer the Hippo pathway's consistent activation by MST-1 helps modulate uncontrolled cell division while in cardiovascular diseases MST-1 plays a role by driving cardiomyocyte apoptosis. MST-1’s interplay with FoxO transcription factors also highlights its contribution to these diseases by reinforcing stress response and DNA repair mechanisms.
