Generation of Straight or Branched Actin Filaments

The straight or branched structure formation of actin filaments is controlled by nucleating proteins such as the formins and Arp2/3 complex. Formin-mediated assembly results in straight filaments, whereas Arp2/3 protein complex-mediated assembly results in branched actin filaments.
Arp2/3 Complex
Arp2/3 complex is a seven-subunit complex consisting of two proteins similar to actin- Arp2 and Arp3, and five other subunits that help keep Arp2 and Arp3 inactive. When required, the complex is...

Conservation of Protein Domains Over Different Proteins

Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to form...
Mechanisms of Membrane Domain Formation00:59

Mechanisms of Membrane Domain Formation

Different physical properties of lipids and proteins allow them to localize and form distinct islands or domains in the membrane. Some membrane domains are formed due to protein-protein interactions, whereas others are formed due to the presence of specific lipids such as sphingolipids and sterols—for example, large proteins, such as bacteriorhodopsin, aggregate and create distinct domains.
Another mechanism for membrane domain formation involves membrane proteins interacting with cytoskeletal...

Area of Science:

  • Computational biology
  • Structural biology
  • Molecular biology

Background:

  • RNA pseudoknotted structures are crucial for cellular functions like transcription, splicing, and translation.
  • Predicting large pseudoknotted RNA folds computationally remains a significant challenge.

Purpose of the Study:

  • To develop an efficient domain-based computational method for predicting complex and large pseudoknotted RNA structures.
  • To reduce the computational complexity of RNA structure prediction.

Main Methods:

  • A domain-based approach was developed, separating large RNAs into distinct structural domains.
  • The method involves identifying domains, predicting structures for each domain, and assembling them into the full structure.
  • Computational time is reduced by approximately N^2 for an N-nucleotide sequence.

Main Results:

  • The model successfully predicts structures for various RNA systems, including human telomerase RNA (hTR), internal ribosome entry site (IRES), and HIV genome.
  • Predicted structures for sequences ranging from 200 to 400 nucleotides show good agreement with experimental data.

Conclusions:

  • The domain-based method provides an effective and computationally efficient solution for predicting large and complex RNA pseudoknotted structures.
  • This approach advances the field of RNA structure prediction and has implications for understanding RNA function.
