Stk4 Gene Summary [Mouse]
Predicted to enable several functions, including ATP binding activity; magnesium ion binding activity; and protein homodimerization activity. Involved in hippo signaling and positive regulation of substrate-dependent cell migration, cell attachment to substrate. Acts upstream of or within several processes, including embryonic organ development; epithelial tube morphogenesis; and positive regulation of apoptotic process. Located in cytoplasm and nucleus. Is expressed in ovary; renal vasculature; and testis. Human ortholog(s) of this gene implicated in primary immunodeficiency disease. Orthologous to human STK4 (serine/threonine kinase 4).

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 Stk4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
