Large tumor suppressor kinase 1 (LATS1) is an enzyme that in humans is encoded by the LATS1 gene. [5] [6] [7]

It has been associated with the Hippo signaling pathway, where it phosphorylates YAP and TAZ to inactivate their function. [8]

The protein encoded by this gene is a putative serine/threonine kinase that localizes to the mitotic apparatus and complexes with cell cycle controller CDC2 kinase in early mitosis. The protein is phosphorylated in a cell-cycle dependent manner, with late prophase phosphorylation remaining through metaphase. The N-terminal region of the protein binds CDC2 to form a complex showing reduced histone H1 kinase activity, indicating a role as a negative regulator of CDC2/cyclin A. In addition, the C-terminal kinase domain binds to its own N-terminal region, suggesting potential negative regulation through interference with complex formation via intramolecular binding. Biochemical and genetic data suggest a role as a tumor suppressor. This is supported by studies in knockout mice showing development of soft-tissue sarcomas, ovarian stromal cell tumors and a high sensitivity to carcinogenic treatments. [7]

Interactions

LATS1 has been shown to interact with Zyxin [9] and Cdk1. [5]

Cyclin-dependent kinase 1 also known as CDK1 or cell division cycle protein 2 homolog is a highly conserved protein that functions as a serine/threonine protein kinase, and is a key player in cell cycle regulation. It has been highly studied in the budding yeast S. cerevisiae, and the fission yeast S. pombe, where it is encoded by genes cdc28 and cdc2, respectively. With its cyclin partners, Cdk1 forms complexes that phosphorylate a variety of target substrates ; phosphorylation of these proteins leads to cell cycle progression.

SCRIB, also known as Scribble, SCRIBL, or Scribbled homolog (Drosophila), is a scaffold protein which in humans is encoded by the SCRIB gene. It was originally isolated in Drosophila melanogaster in a pathway (also known as the Scribble complex) with DLGAP5 (Discs large) and LLGL1 (Lethal giant larvae) as a tumor suppressor. In humans, SCRIB is found as a membrane protein and is involved in cell migration, cell polarity, and cell proliferation in epithelial cells. There is also strong evidence that SCRIB may play a role in cancer progression because of its strong homology to the Drosophila protein.

<span class="mw-page-title-main">Hippo signaling pathway</span> Signaling pathway that controls organ size

The Hippo signaling pathway, also known as the Salvador-Warts-Hippo (SWH) pathway, is a signaling pathway that controls organ size in animals through the regulation of cell proliferation and apoptosis. The pathway takes its name from one of its key signaling components—the protein kinase Hippo (Hpo). Mutations in this gene lead to tissue overgrowth, or a "hippopotamus"-like phenotype.
