Lamb1 Gene Summary [Rat]
Predicted to enable enzyme binding activity; glycosphingolipid binding activity; and integrin binding activity. Predicted to be an extracellular matrix structural constituent. Predicted to be involved in several processes, including basement membrane assembly; neurogenesis; and substrate adhesion-dependent cell spreading. Predicted to act upstream of or within embryo implantation and neuron projection development. Located in collagen-containing extracellular matrix. Human ortholog(s) of this gene implicated in autistic disorder and lissencephaly 5. Orthologous to human LAMB1 (laminin subunit beta 1). [provided by Alliance of Genome Resources, Apr 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 rat Lamb1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
