Predicted to enable ATP binding activity and protein serine/threonine kinase activity. Predicted to be involved in cell surface receptor signaling pathway; intracellular signal transduction; and positive regulation of canonical NF-kappaB signal transduction. Predicted to act upstream of or within protein phosphorylation and signal transduction. Predicted to be active in cytoplasm; nucleus; and plasma membrane. Human ortholog(s) of this gene implicated in ankylosing spondylitis; diffuse scleroderma; psoriatic arthritis; and squamous cell carcinoma. Orthologous to human IRAK1 (interleukin 1 receptor associated kinase 1).
