Tested Applications

• Positive WB detected in: HeLa cells, MCF-7 cells
• Positive IHC detected in: human kidney tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0
• Positive IF/ICC detected in: H9C2 cells

Recommended dilution

• Western Blot (WB): WB : 1:1000-1:8000

Background Information

ERBB2IP is a cytoplasmic protein that contains leucine-rich repeats (LRR) and PSD95/Dlg1/zo-1 (PDZ) domain (thus named a LAP protein). ERBB2IP interacts, via its single PDZ domain, specifically with ErbB2, but not with ErbB3, ErbB4, or EGFR. It is colocalized with ErbB2 at the basolateral membranes of epithelial cells. In addition, ERBB2IP also interacts with PSD‐95, Lano and with three p120‐related catenins, eBPAG1 and the β4 subunit of the α6β4 integrin, two major components of hemidesmosomes. The molecular weight of ERBB2IP was predicted 150~180 kDa by Western Blot.(PMID: 25288731,PMID: 24252174,PMID: 19289088)
