Fstl3 Gene Summary [Mouse]

Enables activin binding activity. Acts upstream of or within negative regulation of BMP signaling pathway. Located in extracellular space. Is expressed in several structures, including brain; foregut; limb; male reproductive gland or organ; and thymus. Orthologous to human FSTL3 (follistatin like 3).

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 Fstl3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
