![]() ![]() This study identifies a complex responsible for the snRNA 3’ end maturation in plants and uncovers a previously unknown function of CPSF73 in snRNA maturation. However, the DSP1 complex does not affect pre-mRNA 3’ end cleavage, suggesting that plants may use different CPSF73-I-containing complexes to process snRNAs and premRNAs. The catalytic component of this complex is likely the cleavage and polyadenylation specificity factor 73 kDa-I (CSPF73-I), which is the nuclease cleaving the pre-mRNA 3’ end. Based on the clinical requirements of temperature control in dental implant surgery, this study aims to establish a theoretical model of the temperature distribution within the bone. We further show that DSP1 forms a conserved complex, which contains at least four additional proteins, to catalyze snRNA 3’ end maturation in Arabidopsis. In addition, DSP1 binds snRNA loci and interacts with Pol-II in a DNA/RNA-dependent manner. Following the detection of a sim300 TeV neutrino potentially associated with the flaring blazar TXS 0506+056, an excess of neutrinos around its position in 2014. Xuejiao Fan, Yunfeng Liu, Jun Tao, Yingying Liu, Kang Li, Zhenwei Ling. A hypomorphic dsp1-1 mutation causes pleiotropic developmental defects, impairs the 3’ end processing of snRNAs, increases the levels of snRNA primary transcripts (pre-snRNAs), and alters the occupancy of Pol II at snRNA loci. Neng-Bin Chang, Xing Liu, Jia-Ying Xu, Dong Liu, Cong-Cong Shi, Wen-Yi Zhang. Here, we show that DEFECTIVE in snRNA PROCESSING 1 (DSP1) is an essential protein for snRNA 3’ end maturation in Arabidopsis. guidelines recommend angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) for all patients with acute myocardial infarction (AMI) in the absence of contraindications as either a Class I or Class IIa recommendation. However, the protein factors responsible for this process remain elusive in plants. The biogenesis of the majority of snRNAs involves 3’ end endonucleolytic cleavage of the nascent transcript from the elongating DNA-dependent RNA ploymerase II. Uridine-rich small nuclear RNAs (snRNAs) are the basal components of the spliceosome and play essential roles in splicing.
