Receptor tyrosine-protein kinase erbB-2
ERBB2
Functioni
Protein tyrosine kinase that is part of several cell surface receptor complexes, but that apparently needs a coreceptor for ligand binding. Essential component of a neuregulin-receptor complex, although neuregulins do not interact with it alone. GP30 is a potential ligand for this receptor. Regulates outgrowth and stabilization of peripheral microtubules (MTs). Upon ERBB2 activation, the MEMO1-RHOA-DIAPH1 signaling pathway elicits the phosphorylation and thus the inhibition of GSK3B at cell membrane. This prevents the phosphorylation of APC and CLASP2, allowing its association with the cell membrane. In turn, membrane-bound APC allows the localization of MACF1 to the cell membrane, which is required for microtubule capture and stabilization (By similarity).
By similarityIn the nucleus is involved in transcriptional regulation. Associates with the 5'-TCAAATTC-3' sequence in the PTGS2/COX-2 promoter and activates its transcription. Implicated in transcriptional activation of CDKN1A; the function involves STAT3 and SRC. Involved in the transcription of rRNA genes by RNA Pol I and enhances protein synthesis and cell growth (By similarity).

Interactioni
Subunit structurei
Homodimer. Heterodimer with EGFR, ERBB3 and ERBB4.

Interacts with PRKCABP and PLXNB1.
Interacts (when phosphorylated on Tyr-1252) with MEMO1.
Interacts with MUC1.
Interacts (when phosphorylated on Tyr-1138) with GRB7 (via SH2 domain).
Interacts (when phosphorylated on Tyr-1252) with ERBIN.
Interacts with SRC, KPNB1, PTK6, RANBP2, EEA1, CRM1, CLTC, RPA194, MYOC and ACTB.
Interacts (preferentially with the tyrosine phosphorylated form) with CPNE3; this interaction occurs at the cell membrane and is increased in a growth factor heregulin-dependent manner.
Interacts with HSP90AA1 and HSP90AB1 in an ATP-dependent manner; the interaction suppresses ERBB2 kinase activity (By similarity).
Interacts with SORL1; this interaction regulates ERBB2 subcellular distribution by promoting its recycling after internalization from endosomes back to the plasma membrane, hence stimulates ERBB2-mediated signaling (By similarity).
