Summary
Mutations in SMN genes cause spinal muscular atrophy. The SMN protein is crucial for assembling cellular ribonucleoprotein particles, impacting motor neuron function.
Area of Science:
- Molecular Biology
- Genetics
- Neuroscience
Background:
- Spinal muscular atrophy (SMA) is a debilitating neuromuscular disorder.
- SMA is linked to mutations or deletions in genes encoding the Survival Motor Neuron (SMN) protein.
Purpose of the Study:
- To investigate the function of the SMN protein.
- To understand the molecular mechanisms underlying SMA.
Main Methods:
- Genetic analysis of SMN genes.
- Biochemical characterization of the SMN protein complex.
Main Results:
- Identified mutations/deletions in SMN genes as causative for SMA.
- Demonstrated that the SMN protein is part of a multi-component complex.
Conclusions:
- The SMN protein complex plays a vital role in cellular ribonucleoprotein particle assembly.
- Dysfunction in SMN protein complex assembly may lead to SMA pathogenesis.

02:41Protein Complex Assembly
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

03:03Amyloid Fibrils
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining, normally used to...

02:53Ribosomal RNA Synthesis
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

02:27Nonsense-mediated mRNA Decay
The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

01:18Assembly of Cytoskeletal Filaments
Cytoskeletal filaments are polymeric forms of smaller protein subunits. However, individual cytoskeletal filaments may easily disassemble or associate with other similar filaments to form rigid structures. Microfilaments, made of actin monomers, rely on actin-binding proteins to form bundles and create networks of individual actin filaments. Microtubules rely on microtubule-associated proteins (MAPs) to form sturdy cylindrical structures. However, the proteins involved in forming complex...
