Enables Toll-like receptor binding activity and interleukin-1 receptor binding activity. Involved in several processes, including cellular response to oxidised low-density lipoprotein particle stimulus; positive regulation of cytokine production; and response to bacterium. Acts upstream of or within several processes, including positive regulation of intracellular signal transduction; regulation of cytokine production; and response to bacterium. Located in cytosol and plasma membrane. Is expressed in cerebral cortex; embryo; and telencephalon. Used to study Coronavirus infectious disease. Human ortholog(s) of this gene implicated in Waldenstroem's macroglobulinemia; colorectal carcinoma; and primary immunodeficiency disease. Orthologous to human MYD88 (MYD88 innate immune signal transduction adaptor). [provided by Alliance of Genome Resources, Apr 2022]
