Q. A researcher is studying a novel receptor kinase involved in cell signaling. The functionally active form of this receptor is a homodimer that forms at the cell membrane upon ligand binding. The researcher isolates a mutant allele that produces a structurally altered, kinase-dead version of the receptor. When a heterozygous cell line (carrying one normal allele and one mutant allele) is generated, signaling is almost completely abolished, mimicking a null phenotype. Biochemical analysis reveals that the mutant protein is stably expressed and still binds to the normal protein.
