Anti-ErbB2 / HER2 antibody [ERB2/776] - BSA and Azide free,Abcam,AB212343

Target data The protein expressed by the ERBB2 gene is a protein tyrosine kinase involved in several cell surface receptor complexes, requiring a coreceptor for ligand binding. It is an essential component of a neuregulin-receptor complex, although neuregulins do not bind to it directly. GP30 is a potential ligand for this receptor. ERBB2 regulates the outgrowth and stabilization of peripheral microtubules (MTs) via the MEMO1-RHOA-DIAPH1 signaling pathway, which, upon activation, phosphorylates and inhibits GSK3B at the cell membrane. This prevents APC and CLASP2 phosphorylation, allowing their association with the cell membrane, facilitating MACF1 localization necessary for microtubule capture and stabilization. In the nucleus, ERBB2 is involved in transcriptional regulation, associating with the 5'-TCAAATTC-3' sequence in the PTGS2/COX-2 promoter to activate transcription. It is implicated in the transcriptional activation of CDKN1A, involving STAT3 and SRC, and participates in the transcription of rRNA genes by RNA Pol I, thereby enhancing protein synthesis and cell growth.
