Regulation of SMN protein stability.
Spinal muscular atrophy (SMA) is caused by mutations of the survival of motor neuron (SMN1) gene and deficiency of full-length SMN protein (FL-SMN). All SMA patients retain one or more copies of the SMN2 gene, but the principal protein product of SMN2 lacks exon 7 (SMNDelta7) and is unable to compensate for a deficiency of FL-SMN. SMN is known to oligomerize and form a multimeric protein comple...
متن کاملBioinformatics Analysis of Upstream Region and Protein Structure of Fungal Phytase Gene
Phytase increases the bioavailability of phytate phosphorus in seed-based animal feeds and reduces the phosphorus pollution of animal waste. Since most animal feeds for pellets are heated up to 65-80 °C, the production of a thermostable structure for phytase can be useful. In this study, we sought to perform bioinformatics analysis of the upstream region and protein structure of fungal phytase ...
متن کاملA non-sequence-specific requirement for SMN protein activity: the role of aminoglycosides in inducing elevated SMN protein levels.
Spinal muscular atrophy (SMA) is caused by homozygous loss of the survival motor neuron (SMN1) gene. In virtually all SMA patients, a nearly identical copy gene is present, SMN2. SMN2 cannot fully compensate for the loss of SMN1 because the majority of transcripts derived from SMN2 lack a critical exon (exon 7), resulting in a dysfunctional SMN protein. Therefore, the critical distinction betwe...
متن کاملSolution structure of the core SMN–Gemin2 complex
In humans, assembly of spliceosomal snRNPs (small nuclear ribonucleoproteins) begins in the cytoplasm where the multi-protein SMN (survival of motor neuron) complex mediates the formation of a seven-membered ring of Sm proteins on to a conserved site of the snRNA (small nuclear RNA). The SMN complex contains the SMN protein Gemin2 and several additional Gemins that participate in snRNP biosynth...
متن کاملCharacterization of functional domains of the SMN protein in vivo.
The Survival of Motor Neurons (SMN) is the disease gene of spinal muscular atrophy. We have previously established a genetic system based on the chicken pre-B cell line DT40, in which expression of SMN protein is regulated by tetracycline, to study the function of SMN in vivo. Depletion of SMN protein is lethal to these cells. Here we tested the functionality of mutant SMN proteins by determini...
