Structural variability of the ubiquitin specific protease DUSP-UBL double domains.

abstract：:Ribonucleoprotein complexes, which contain mRNAs and their regulator proteins, carry out post-transcriptional control of gene expression. The function of many RNA-binding proteins depends on their association with cofactors. Here, we use a genomic approach to identify transcripts associated with DLC-1, a protein previ...
