Fstl4 Gene Summary [Rat]

Predicted to enable brain-derived neurotrophic factor binding activity. Predicted to be involved in cell differentiation and regulation of BMP signaling pathway. Predicted to act upstream of or within negative regulation of brain-derived neurotrophic factor receptor signaling pathway; negative regulation of collateral sprouting; and negative regulation of dendritic spine development. Predicted to be located in secretory granule. Predicted to be active in extracellular region. Orthologous to human FSTL4 (follistatin like 4). [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 rat Fstl4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
