Ksr1 Gene Summary [Mouse]
Enables several functions, including 14-3-3 protein binding activity; ATP binding activity; and Hsp90 protein binding activity. Involved in Ras protein signal transduction; regulation of MAP kinase activity; and regulation of cell population proliferation. Acts upstream of or within positive regulation of MAPK cascade. Predicted to be located in cytosol and intracellular membrane-bounded organelle. Predicted to be part of protein-containing complex. Predicted to be active in endoplasmic reticulum and membrane. Is expressed in several structures, including brain; genitourinary system; gut; hemolymphoid system gland; and lung. Human ortholog(s) of this gene implicated in breast adenocarcinoma. Orthologous to human KSR1 (kinase suppressor of ras 1). [provided by Alliance of Genome Resources, Apr 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 Ksr1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
