※ U body introduction

    U body is uridine-rich small nuclear ribonucleoproteins (U snRNPs). Drosophila SMN complex proteins Gemin2, Gemin3, and Gemin5 are components of U bodies (1). And U bodies have recently been described in human cells as discrete 200-400 nm nonmembranous cytoplasmic microdomains containing uridine-rich small nuclear ribonucleoproteins U1, U2, U4/U6 and U5 (U snRNPs). U bodies may be involved in snRNP and mRNA assembly and/or transport (2). U snRNPs are assembled in the cytoplasm into U bodies, which also contain essential snRNP (splicesome) assembly factors, suggesting that U bodies are sites for assembly or storage of snRNPs before being imported into the nucleus (3).
