Function:Acts as an adapter for the receptor ERBB2 , in epithelia. By binding the unphosphorylated 'Tyr-1248' of receptor ERBB2 , it may contribute to stabilize this unphosphorylated state. ,sequence Caution:Contaminating sequence. Potential poly-A sequence. ,similarity:Belongs to the LAP (LRR and PDZ) protein family. ,similarity:Contains 1 PDZ (DHR) domain. ,similarity:Contains 17 LRR (leucine-rich) repeats. ,subcellular location:Found in hemidesmosomes , which are cell-substrate adhesion complexes in stratified epithelia. In transfected cells , either diffusely distributed over the cytoplasm or concentrated at the basolateral membrane. ,subunit:Interacts with ERBB2 , BPAG1 and ITGB4. May favor the localization of ERBB2 , by restricting its presence to the basolateral membrane of epithelial cells. Also found to interact with ARVCF and delta catenin. ,tissue specificity:Highly expressed in brain , heart , kidney , muscle and stomach , followed by liver , spleen and intestine. ,
