Predicted to enable signaling receptor binding activity. Predicted to be involved in several processes, including cellular response to tumor necrosis factor; negative regulation of nucleotide-binding activity oligomerization domain containing 2 signaling pathway; and regulation of gene expression. Predicted to act upstream of or within protein targeting. Is active in glutamatergic synapse; neuromuscular junction; and postsynaptic specialization. Orthologous to human ERBIN (erbb2 interacting protein). [provided by Alliance of Genome Resources, Apr 2022]
