Predicted to enable natural killer cell lectin-like receptor binding activity and protein homodimerization activity. Predicted to act upstream of or within several processes, including T cell receptor signaling pathway; regulation of actin filament polymerization; and regulation of interleukin-2 production. Predicted to be located in cell surface and plasma membrane. Predicted to be active in external side of plasma membrane. Orthologous to human CLEC2D (C-type lectin domain family 2 member D).
