RNA-Seq analysis of wild-type and ttpA-C240ins mutant D. discoideum amebae in surface and liquid growth

ABSTRACT: In many eukaryotes, mRNAs containing specific AU-rich motifs are regulated by proteins of the tristetraprolin (TTP) family, which bind to these motifs through a tandem zinc finger (TZF) domain. This binding leads to promotion of subsequent deadenylation and decay, partly through a conserved carboxyl-terminal CNOT1 binding domain. We explored the physiological role of the single TTP family member (TtpA) expressed in Dictyostelium discoideum. This study shows the effect of an insertional mutation within the TZF domain (ttpA-C240ins), which creates a null genotype, evaluated in amebae in growth medium during surface culture and liquid culture under axenic conditions. The mutant cells exhibited severe growth defects and a multinucleate phenotype during liquid culture, but not in surface culture.

RNA-Seq analysis of wild-type and ttpA-C240ins mutant D. discoideum amebae during short-term nutrient deprivation

Project description:In many eukaryotes, mRNAs containing specific AU-rich motifs are regulated by proteins of the tristetraprolin (TTP) family, which bind to these motifs through a tandem zinc finger (TZF) domain. This binding leads to promotion of subsequent deadenylation and decay, partly through a conserved carboxyl-terminal CNOT1 binding domain. We explored the physiological role of the single TTP family member (TtpA) expressed in Dictyostelium discoideum. This study shows the effect of an insertional mutation in the TZF domain (ttpA-C240ins), which disrupted the TZF RNA binding domain, evaluated in amebae in axenic conditions in growth medium during surface culture, and during short term (2 and 6 hours) nutrient deprivation. RNA-Seq analysis was performed on WT and mutant cells in parallel during this short time course.

RNA-Seq analysis of wild-type and ttpA-D450trx mutant D. discoideum amebae

Project description:In many eukaryotes, mRNAs containing specific AU-rich motifs are regulated by proteins of the tristetraprolin (TTP) family, which bind to these motifs through a tandem zinc finger (TZF) domain. This binding leads to promotion of subsequent deadenylation and decay, partly through a conserved carboxyl-terminal CNOT1 binding domain. We explored the physiological role of the single TTP family member (TtpA) expressed in Dictyostelium discoideum. This study shows the effect of a carboxyl-terminal truncation (ttpA-D450trx), which removed the predicted CNOT1 binding domain, evaluated in amebae in growth medium during surface culture. The cells exhibited external and gene expression phenotypes that were very similar to those of two distinct null mutants, raising the possibility that this domain is necessary for TtpA-promoted mRNA decay in this species.

RNA-Seq analysis of wild-type and ttpA-C231S, ttpA-E236fsx, and ttpA-Y242fsx mutant D. discoideum amebae

Project description:In many eukaryotes, mRNAs containing specific AU-rich motifs are regulated by proteins of the tristetraprolin (TTP) family, which bind to these motifs through a tandem zinc finger (TZF) domain. This binding leads to promotion of subsequent deadenylation and decay, partly through a conserved carboxyl-terminal CNOT1 binding domain. We explored the physiological role of the single TTP family member (TtpA) expressed in Dictyostelium discoideum. This study shows the effect of three distinct putative null mutations in the ttpA gene on transcript expression in amebae in growth medium during surface culture under axenic conditions. The cells exhibited similar external and gene expression phenotypes, suggesting that they are all null mutants, despite two different types of mutations (two frame shifts and one amino acid substitution).

Sequences in the cytoplasmic tail of SARS-CoV-2 Spike facilitate expression at the cell surface and syncytia formation

Project description:The spike (S) protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) binds the cell surface protein ACE2 to mediate fusion of the viral membrane with target cells1-4. S comprises a large external domain, a transmembrane domain (TMD) and a short cytoplasmic tail5,6. To elucidate the intracellular trafficking of S protein in host cells we applied proteomics to identify cellular factors that interact with its cytoplasmic tail. We confirm interactions with components of the COPI, COPII and SNX27/retromer vesicle coats, and with FERM domain actin regulators and the WIPI3 autophagy component. The interaction with COPII promotes efficient exit from the endoplasmic reticulum (ER), and although COPI-binding should retain S in the early Golgi system where viral budding occurs, the binding is weakened by a suboptimal histidine residue in the recognition motif. As a result, S leaks to the surface where it accumulates as it lacks an endocytosis motif of the type found in many other coronaviruses7-10. It is known that when at the surface S can direct cell:cell fusion leading to the formation of multinucleate syncytia7-9. Thus, the trafficking signals in the cytoplasmic tail of S protein indicate that syncytia formation is not an inadvertent by-product of infection but rather a key aspect of the replicative cycle of SARS-CoV-2 and potential cause of pathological symptoms.

Differential Gene Expression and mRNA decay in Wild-Type and Myeloid-specific TTP Family Member Triple (M-Triple) Knock-out macrophages using RNA-Seq

Project description:Members of the tristetraprolin (TTP) family of RNA-binding proteins can bind to and promote the decay of specific transcripts containing AU-rich motifs. ZFP36 (TTP) is best known for regulating cytokine expression in myeloid cells; however, the mammalian paralogues ZFP36L1 and ZFP36L2 have not been viewed as important in controlling inflammation. To study potential functional overlaps of these three TTP family proteins in myeloid cells, we developed myeloid-specific knock-out (M-KO) mice of these genes, singly and together. M-Zfp36-KO mice exhibited a mild inflammatory syndrome late in life, while M-Zfp36l1-KO and M-Zfp36l2-KO mice had no apparent spontaneous phenotypes. Mice with simultaneous deficiency of all three TTP family members in myeloid cells developed a severe, spontaneous, inflammatory phenotype, with a median survival of 8 weeks. Macrophages derived from these mice contained many more stabilized transcripts than cells from M-Zfp36-KO mice, many encoding pro-inflammatory cytokines and chemokines. Our findings emphasize the importance of all three family members, acting in concert, in myeloid cell function.
