Stk3 Gene Summary [Mouse]
Predicted to enable several functions, including ATP binding activity; magnesium ion binding activity; and transcription regulator activator activity. Involved in hippo signaling. Acts upstream of or within several processes, including chordate embryonic development; hepatocyte apoptotic process; and regulation of signal transduction. Located in cytoplasm. Is expressed in cerebral cortex; genitourinary system; and lung. Orthologous to human STK3 (serine/threonine kinase 3). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Stk3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
