Ksr1 Gene Summary [Rat]
Enables mitogen-activated protein kinase kinase binding activity. Predicted to be involved in Ras protein signal transduction; regulation of MAP kinase activity; and regulation of cell population proliferation. Predicted to act 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. 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 rat 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.
