Predicted to enable polyubiquitin modification-dependent protein binding activity and protein kinase binding activity. Predicted to be involved in several processes, including cell surface receptor signaling pathway; positive regulation of leukocyte activation; and toll-like receptor signaling pathway. Predicted to act upstream of or within I-kappaB kinase/NF-kappaB signaling. Predicted to be located in cytosol and nucleoplasm. Orthologous to human TNIP2 (TNFAIP3 interacting protein 2).
