Erbb3 - erb-b2 receptor tyrosine kinase 3

Enables neuregulin binding activity and neuregulin receptor activity. Involved in several processes, including animal organ development; cellular response to insulin stimulus; and positive regulation of glucose import. Located in nucleus and postsynaptic membrane. Biomarker of chronic obstructive pulmonary disease and median neuropathy. Human ortholog(s) of this gene implicated in lethal congenital contracture syndrome 2; lung adenocarcinoma; lung non-small cell carcinoma; and neuronal intestinal dysplasia type A. Orthologous to human ERBB3 (erb-b2 receptor tyrosine kinase 3). [provided by Alliance of Genome Resources, Apr 2022]
