The family of WW domain-containing proteins contains over 2000 members. The small WW domain module is responsible, in part, for protein/protein binding interactions and signaling. Many of these proteins are located at the membrane/cytoskeleton area, where they act as adaptors to receive signals from the cell surface. In this review, we provide molecular insights regarding recent novel findings on signaling from the cell surface toward WW domain-containing oxidoreductase, known as WWOX, FOR or WOX1. More specifically, transforming growth factor beta 1 utilizes cell surface hyaluronidase Hyal-2 (hyaluronoglucosaminidase 2) as a cognate receptor for signaling with WWOX and Smad4 to control gene transcription, growth and death. Complement C1q alone, bypassing the activation of classical pathway, signals a novel event of apoptosis by inducing microvillus formation and WWOX activation. Deficiency in these signaling events appears to favorably support cancer growth.
