LATS2 also known as Large Tumor Suppressor kinase 2 is a serine/threonine-protein kinase with a molecular mass of approximately 121 kDa. It functions as a component of the Hippo signaling pathway where it helps regulate cell proliferation apoptosis and organ size. LATS2 shows expression in various tissues with notable levels in the lung heart and liver. Its role in these tissues makes it an important target for research in cancer and developmental biology.
Biological function summary

LATS2 plays an important role in cell cycle regulation and tumor suppression. LATS2 forms part of the core kinase complex within the Hippo pathway working closely with other proteins like MST1/2 kinases and Scaffold proteins SAV1. Through phosphorylation LATS2 can inhibit the activity of YAP and TAZ transcription co-activators promoting cell contact inhibition and proper tissue architecture. Its activity is important for limiting excessive cell growth and ensuring accurate cell division.

Pathways

LATS2 integrates into the Hippo signaling pathway and influences the PI3K-AKT signaling pathway. Within the Hippo pathway LATS2 interacts with MST1/2 forming an upstream kinase complex activating through phosphorylation of downstream transcription co-activators YAP and TAZ. These interactions result in the transcriptional regulation of genes controlling cell growth and apoptosis. Overlap with the PI3K-AKT pathway links LATS2 to cellular processes related to growth migration and survival providing a critical nexus that communicates cell status and environmental cues.

LATS2 has associations with both cancer and cardiac hypertrophy. In cancer dysregulation of LATS2 activity can result in aberrant cell growth and tumor development often noted in different types of carcinomas where it can act as a tumor suppressor. Mutations or reduced expression of LATS2 can correlate with increased cancer progression implying a need for comprehensive understanding of its regulation and function. Additionally in cardiac hypertrophy LATS2 contributes to cardiac cell size regulation and its imbalance can connect to abnormal heart muscle thickening. In these contexts LATS2 interaction with proteins such as YAP and TAZ provides an important point of interest for therapeutic interventions.

General info

Function

Negative regulator of YAP1 in the Hippo signaling pathway that plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis (PubMed : 18158288, PubMed : 26437443, PubMed : 26598551, PubMed : 34404733). 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 (PubMed : 26437443, PubMed : 26598551, PubMed : 34404733). Phosphorylation of YAP1 by LATS2 inhibits its translocation into the nucleus to regulate cellular genes important for cell proliferation, cell death, and cell migration (PubMed : 26598551, PubMed : 34404733). Also phosphorylates YAP1 in response to cell contact inhibition-driven WWP1 ubiquitination of AMOTL2, which results in LATS2 activation (PubMed : 34404733). Acts as a tumor suppressor which plays a critical role in centrosome duplication, maintenance of mitotic fidelity and genomic stability (PubMed : 10871863). Negatively regulates G1/S transition by down-regulating cyclin E/CDK2 kinase activity (PubMed : 12853976). Negative regulator of the androgen receptor (PubMed : 15131260). Phosphorylates SNAI1 in the nucleus leading to its nuclear retention and stabilization, which enhances its epithelial-mesenchymal transition and tumor cell invasion/migration activities (PubMed : 21952048). This tumor-promoting activity is independent of its effects upon YAP1 or WWTR1/TAZ (PubMed : 21952048). Acts as an activator of the NLRP3 inflammasome by mediating phosphorylation of 'Ser-265' of NLRP3 following NLRP3 palmitoylation, promoting NLRP3 activation by NEK7 (PubMed : 39173637).

Sequence similarities

Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family.

Post-translational modifications

Autophosphorylated and phosphorylated during M-phase and the G1/S-phase of the cell cycle (PubMed:15147269, PubMed:21952048). Phosphorylated and activated by STK3/MST2 (PubMed:15688006). Phosphorylated by MAP4Ks; in parallel to STK3/MST2 and resulting to its activation (PubMed:26437443). Phosphorylation by NUAK2 may regulate its activity in phosphorylation and inactivation YAP1 (PubMed:32845958).
