Predicted to enable signaling receptor binding activity. Predicted to be involved in parturition. Predicted to act upstream of or within several processes, including T cell activation via T cell receptor contact with antigen bound to MHC molecule on antigen presenting cell; negative regulation of antigen processing and presentation; and negative regulation of memory T cell differentiation. Predicted to be active in collagen-containing extracellular matrix and extracellular space. Orthologous to human FGL2 (fibrinogen like 2). [provided by Alliance of Genome Resources, Apr 2022]
