LATS2 (large tumor suppressor kinase 2) is a central kinase in the Hippo signaling pathway that functions as a tumor suppressor by restricting cell proliferation and promoting apoptosis 1. As part of the conserved Hippo kinase cascade, LATS2 is activated by upstream kinases MST1/2 and subsequently phosphorylates and inactivates the transcriptional coactivators YAP and TAZ, preventing their nuclear translocation and oncogenic transcriptional programs 1. Beyond the canonical Hippo pathway, LATS2 exhibits diverse regulatory functions including heavy metal homeostasis through phosphorylation and inhibition of MTF1, a key transcription factor in heavy metal response 2. In cardiac physiology, LATS1/2 maintain sinoatrial node homeostasis by regulating calcium handling genes and preventing fibrosis through YAP/TAZ control 3. LATS2 is clinically relevant in cancer progression, where its downregulation contributes to metastasis - fatty liver-derived extracellular vesicles suppress LATS2 through microRNAs, enhancing YAP activity and promoting colorectal cancer liver metastasis 4. Additionally, LATS2 inhibition by ZIP4-mediated signaling promotes epithelial-mesenchymal transition plasticity in pancreatic cancer 5. The differential expression patterns and binding partners of LATS1 and LATS2 suggest specialized functions despite their overlapping roles 6.
