The G-patch protein Cwf28 interacts with the RNA helicase Cdc28 in catalytically active spliceosomes in Schizosaccharomyces pombe
G-patch proteins are emerging as key regulatory cofactors of DEAH-box RNA helicases involved in pre-mRNA splicing, yet the functions of many family members remain poorly understood. Here, we characterize the conserved G-patch domain–containing protein Cwf28 from Schizosaccharomyces pombe, an essential factor with a pre...
