Scaffolding proteins play pivotal roles in the assembly of macromolecular machines such as the *** adaptor protein cd2bp2,originally identified as a binding partner of the adhesion molecule cd2,is a pre-spliceosomal assembly factor that utilizes its glycine-tyrosine-phenylalanine(GYF)domain to co-localize with spliceosomal *** far,its function in vertebrates is *** conditional gene targeting in mice,we show that cd2bp2 is crucial for embryogenesis,leading to growth retardation,defects in vascularization,and premature death at embryonic day 10.5 when *** of the protein in bone marrow-derived macrophages indicates that cd2bp2 is involved in the alternative splicing of mRNA transcripts from diverse *** the molecular level,we identified the phosphatase PP1 to be recruited to the spliceosome via the N-terminus of *** the strong expression of cd2bp2 in podocytes of the kidney,we use selective depletion of cd2bp2,in combination with next-generation sequencing,to monitor changes in exon usage of genes critical for podocyte functions,including VEGF and actin ***2bp2-depleted podocytes display foot process effacement,and cause proteinuria and ultimately lethal kidney failure in ***,our study defines cd2bp2 as a non-redundant splicing factor essential for embryonic development and podocyte integrity.
