Lrp4 Gene Summary [Rat]
Enables apolipoprotein binding activity; receptor tyrosine kinase binding activity; and scaffold protein binding activity. Involved in dendrite morphogenesis and synapse organization. Located in several cellular components, including plasma membrane raft; postsynaptic density; and synaptic membrane. Human ortholog(s) of this gene implicated in Cenani-Lenz syndactyly syndrome; congenital myasthenic syndrome 17; and sclerosteosis 2. Orthologous to human LRP4 (LDL receptor related protein 4).

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 Lrp4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
