GRB7 [ENSP00000310771]
growth factor receptor-bound protein 7; Interacts with the cytoplasmic domain of the epidermal growth factor receptor which is then inhibited. The interaction is mediated by the SH2 domain. Also binds to ERBB2
ERBB3 [ENSP00000267101]
v-erb-b2 erythroblastic leukemia viral oncogene homolog 3 (avian); Binds and is activated by neuregulins and NTAK
