DEAD-box proteins
How are they identified? Originally, these proteins were identified by genetic approaches. Comparison of their amino acid sequences revealed a high degree of conservation of eight different motifs. They are present in a core region that is flanked by 5′ and 3′ external sequences of various length. The systematic sequencing of genomes, reverse genetics and genetic methods have revealed the wides...
متن کاملfunctional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner
نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...
The DEAD-box helicase Mss116 plays distinct roles in mitochondrial ribogenesis and mRNA-specific translation
Members of the DEAD-box family are often multifunctional proteins involved in several RNA transactions. Among them, yeast Saccharomyces cerevisiae Mss116 participates in mitochondrial intron splicing and, under cold stress, also in mitochondrial transcription elongation. Here, we show that Mss116 interacts with the mitoribosome assembly factor Mrh4, is required for efficient mitoribosome biogen...
متن کاملFunctional Annotation of Two Hypothetical Proteins Reveals Valuable Proteins Involved in Response to Salinity: An in silico Approach
Through the exponential development in the specification of sequences and structures of proteins by genome sequencing and structural genomics approaches, there is a growing demand for valid bioinformatics methods to define these proteins function. In this study, our objective is to identify the function of unknown proteins from UCB-1 pistachio rootstock and specify their class...
متن کاملmRNA export: Travelling with DEAD box proteins
Recent studies have shown that the putative RNA helicase protein UAP56 and its yeast homologue Sub2p are not only involved in pre-mRNA splicing but also required for the export of mRNA out of the nucleus, even if the mRNA is encoded by an intron-less gene.
