Erbin (protein)

From Wikipedia, the free encyclopedia

Discovered in 1997, Erbin is a 200kDa protein containing a PDZ domain.[1] Erbin's C-terminal PDZ domain is able to bind to ErbB2, a protein tyrosine kinase which is often associated with poor prognosis in epidermal oncogenesis.[2] Erbin's N-terminal region has been shown to disrupt Ras to Raf binding and may be, through this action, a tumor suppressing protein.[3]

Erbin is named after its ability to bind ErbB2, though it shares a name with Saint Erbin, a 5th century Cornish monk. This has led some to suggest that Saint Erbin may be the patron saint of both PDZ domains and ErbB protein kinase receptors.
