Interactioni

Subunit structurei

Monomer (PubMed:12949241). Interacts with ERBB2 (preferentially with the tyrosine phosphorylated form); this interaction occurs at the cell membrane and is increased in a growth factor heregulin-dependent manner (PubMed:20010870). Interacts with SHC1; this interaction may mediate the binding of CPNE3 with ERBB2 (PubMed:20010870). Interacts with RACK1 (PubMed:20010870).2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
