The WW domain represents a small and compact globular structure that interacts with proline-rich ligands. WW domain-binding protein 4 (WBP4) is a general spliceosomal protein that may play a role in cross-intron bridging of U1 and U2 snRNPs in the spliceosomal complex A [taken from NCBI Entrez Gene (Gene ID: 11193)].
