Protein Folding Quality Check in the RER01:29

Protein Folding Quality Check in the RER

5.3K
ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...

Protein and Protein Structure

89.5K
Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective. They may serve in transport, storage, or membranes; or they may be toxins or enzymes. Their structures, like their functions, vary greatly. They are all, however, amino acid polymers arranged in a linear sequence.
A protein's shape is critical to its function. For example, an enzyme...

RNA Structure

79.3K
Overview
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
Different Types of RNA Have the Same Basic Structure
There are three main types of ribonucleic acid (RNA): messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). All three RNA types consist of a...

Protein Organization

9.7K
Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.
The primary structure of a protein is its amino acid sequence....

Area of Science:

  • Structural biology
  • Computational biology
  • Bioinformatics

Background:

  • RNA-protein interactions are fundamental to numerous biological processes.
  • Understanding the mechanism of these interactions necessitates knowledge of their three-dimensional (3D) structures.

Purpose of the Study:

  • To introduce 3dRPC, an algorithm for predicting 3D RNA-protein complex structures.
  • To present the newly developed web server for 3dRPC, enabling user-friendly access.
  • To provide a tool that can incorporate experimental or theoretical interface information for improved prediction accuracy.

Main Methods:

  • 3dRPC integrates a docking algorithm (RPDOCK) and a knowledge-based scoring function (3dRPC-Score).
  • RPDOCK samples complex conformations by evaluating geometric, electrostatic, and stacking interactions at the RNA-protein interface.
  • 3dRPC-Score utilizes nucleotide-amino acid pair conformations as statistical variables to select near-native structures.

Main Results:

  • The 3dRPC algorithm effectively predicts 3D RNA-protein complex structures.
  • A web server has been developed, making 3dRPC readily accessible to users without local installation.
  • The server accepts RNA and protein structures in PDB format and can integrate interface information.
