RNA-binding protein with serine-rich domain 1 (RNPS1) is a component of pre-splicing and post-splicing multiprotein complexes, which activates constitutive and alternative splicing. RNPS1 participates in the formation of the spliceosome and activates the pre-mRNA splicing process. In the present study, we found that ubiquitin-specific protease 4 (USP4) is a binding partner of RNPS1. Although RNPS1 is polyubiquitinated by both K48- and K63-linkages, USP4 exclusively deubiquitinates K63-linked
polyubiquitin
chains of RNPS1. We also demonstrate that the catalytic activity of USP4 on ubiquitinated RNPS1 is elevated by
squamous cell carcinoma antigen recognized by T cells 3
(Sart3).
