Fcer1g Gene Summary [Rat]
Enables protein heterodimerization activity and protein homodimerization activity. Predicted to be involved in several processes, including antigen processing and presentation of exogenous peptide antigen via MHC class II; cell surface receptor signaling pathway; and defense response to other organism. Predicted to act upstream of or within several processes, including negative regulation of mast cell apoptotic process; positive regulation of cytokine production; and positive regulation of immune effector process. Part of Fc-gamma receptor III complex. Orthologous to human FCER1G (Fc epsilon receptor Ig). [provided by Alliance of Genome Resources, Apr 2025]
