Lamb2 Gene Summary [Rat]
Predicted to enable integrin binding activity. Predicted to be a structural constituent of synapse-associated extracellular matrix. Predicted to be involved in several processes, including axon guidance; basement membrane assembly; and substrate adhesion-dependent cell spreading. Predicted to act upstream of or within several processes, including metanephric glomerulus development; neurogenesis; and visual perception. Predicted to be located in basement membrane and synapse. Predicted to be part of laminin-3 complex. Predicted to be active in neuromuscular junction and synaptic cleft. Used to study proteinuria. Human ortholog(s) of this gene implicated in Pierson syndrome; nephrotic syndrome type 5; and primary open angle glaucoma. Orthologous to human LAMB2 (laminin subunit beta 2).

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 Lamb2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
