Predicted to enable polyubiquitin modification-dependent protein binding activity and protein kinase binding activity. Involved in several processes, including cell surface receptor signaling pathway; positive regulation of leukocyte activation; and toll-like receptor signaling pathway. Acts upstream of or within I-kappaB kinase/NF-kappaB signaling. Located in cytoplasm. Orthologous to human TNIP2 (TNFAIP3 interacting protein 2). [provided by Alliance of Genome Resources, Apr 2022]
