TNIP2 binds to the C-terminal zinc finger domain of A20 (TNFAIP3; MIM 191163) and is involved in activation of the ERK (see MAPK3; MIM 601795) MAP kinase pathway in various cell types (Van Huffel et al., 2001 [PubMed 11390377]; Papoutsopoulou et al., 2006 [PubMed 16633345]).[supplied by OMIM, Mar 2008]
