Ms4a1 - membrane spanning 4-domains A1

Enables epidermal growth factor receptor binding activity. Predicted to be involved in several processes, including B cell receptor signaling pathway; calcium ion transport; and protein tetramerization. Predicted to act upstream of or within response to bacterium. Predicted to be located in external side of plasma membrane; nucleoplasm; and plasma membrane raft. Biomarker of glomerulonephritis. Human ortholog(s) of this gene implicated in common variable immunodeficiency. Orthologous to human MS4A1 (membrane spanning 4-domains A1). [provided by Alliance of Genome Resources, Apr 2022]
