WW domain-binding protein 1 (WBP1)

WW domain-binding protein 1 (WBP1) is a human protein encoded by the *WBP1* gene, primarily recognized for binding to WW domains—protein motifs involved in diverse signaling and structural cellular processes[1][2][3]. The globular WW domain motif mediates protein-protein interactions by binding polyproline ligands and the XPPXY motif, allowing WBP1 to interact with proteins such as the Yes kinase-associated protein[1][2]. While WBP1 serves as an essential signaling adaptor and is implicated in regulatory networks, its precise biological function and role in specific diseases are not well characterized, and it is not established as a direct therapeutic target or biomarker[1][2][3].
