Mammalian Sterile 20-like kinase 1 (MST1), also known as STK4. is a serine/threonine kinase belonging to the STE20 family, named after its homology to the yeast Sterile 20 kinase. It plays a central role in the Hippo signaling pathway, a conserved regulator of organ size, tissue homeostasis, and tumor suppression. MST1 acts as a key upstream kinase that, upon activation, phosphorylates downstream effectors like LATS1/2. initiating a signaling cascade that ultimately inhibits the YAP/TAZ transcriptional co-activators. This pathway regulates cell proliferation, apoptosis, and differentiation, with dysregulation linked to cancer, immune disorders, and neurodegenerative diseases.
Recombinant human MST1 protein is engineered using expression systems like *E. coli* or mammalian cells to produce functional, purified MST1 for research. It retains kinase activity, enabling studies on its molecular interactions, substrate specificity, and regulatory mechanisms. MST1 is particularly significant in immune regulation, influencing T-cell activation, migration, and survival. Its cleavage by caspases during apoptosis generates an active fragment that amplifies cell death signals. Structurally, MST1 contains an N-terminal regulatory domain with dimerization motifs and caspase cleavage sites, and a C-terminal kinase domain. Recombinant MST1 is essential for drug discovery, pathway analysis, and exploring therapeutic strategies targeting Hippo signaling in diseases like cancer and autoimmune conditions.
