Integrins also bind to many PTBdomain-containing proteins (Calderwood et al., 2003) – including Dok1 and integrincytoplasmic-domain-associated protein 1 (ICAP1) – and these can compete with talin for binding to integrin and so can impair activation

Here we show that the cell-surface transmembrane E3 ubiquitin ligase zinc and ring finger 3 (ZNRF3) and its homologue ring finger 43 (RNF43) are negative feedback regulators of Wnt signalling. ZNRF3 is associated with the Wnt receptor complex, and inhibits Wnt signalling by promoting the turnover of frizzled and LRP6.
