Predicted to enable protein homodimerization activity and signaling receptor binding activity. Predicted to be involved in several processes, including cell surface receptor signaling pathway; myeloid cell activation involved in immune response; and regulation of cytokine production. Predicted to act upstream of or within osteoclast differentiation and regulation of osteoclast development. Predicted to be located in plasma membrane. Predicted to be integral component of plasma membrane. Predicted to be active in cell surface. Biomarker of rheumatoid arthritis. Human ortholog(s) of this gene implicated in Nasu-Hakola disease. Orthologous to human TYROBP (transmembrane immune signaling adaptor TYROBP). [provided by Alliance of Genome Resources, Apr 2022]
