Hapln1 Gene Summary [Mouse]
Predicted to enable hyaluronic acid binding activity. Predicted to be an extracellular matrix structural constituent conferring compression resistance. Predicted to be involved in central nervous system development and skeletal system development. Located in extracellular matrix. Is active in synapse. Is expressed in several structures, including brain; cartilage; genitourinary system; heart; and limb. Used to study spondyloepiphyseal dysplasia congenita. Orthologous to human HAPLN1 (hyaluronan and proteoglycan link protein 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 Hapln1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
