Ltbp1 Gene Summary [Mouse]
Predicted to enable several functions, including microfibril binding activity; receptor ligand inhibitor activity; and transforming growth factor beta binding activity. Acts upstream of or within aorta development; coronary vasculature development; and ventricular septum development. Located in microfibril. Is expressed in several structures, including embryo mesenchyme; forebrain; genitourinary system; heart; and integumental system. Human ortholog(s) of this gene implicated in cutis laxa. Orthologous to human LTBP1 (latent transforming growth factor beta binding 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 Ltbp1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
