Icos Gene Summary [Rat]
Predicted to enable signaling receptor activity. Involved in T cell costimulation; T cell tolerance induction; and cell-cell adhesion. Predicted to be located in external side of plasma membrane. Predicted to be active in plasma membrane. Used to study myocarditis. Biomarker of colitis and uveitis. Human ortholog(s) of this gene implicated in celiac disease; common variable immunodeficiency 1; and immunoglobulin alpha deficiency. Orthologous to human ICOS (inducible T cell costimulator).

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