Igsf1 Gene Summary [Rat]
Enables coreceptor activity. Predicted to be involved in immune response-regulating signaling pathway; negative regulation of activin receptor signaling pathway; and regulation of DNA-templated transcription. Predicted to be located in extracellular region. Predicted to be active in membrane. Human ortholog(s) of this gene implicated in IGSF1 deficiency syndrome. Orthologous to human IGSF1 (immunoglobulin superfamily member 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 rat Igsf1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
