Llgl1 Gene Summary [Mouse]
Predicted to enable GTPase activator activity; enzyme binding activity; and myosin II binding activity. Acts upstream of or within maintenance of apical/basal cell polarity. Located in several cellular components, including basolateral plasma membrane; cytoskeleton; and myelin sheath abaxonal region. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human LLGL1 (LLGL scribble cell polarity complex component 1). [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 Llgl1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
