IP3/DAG Signaling Pathway01:11

IP3/DAG Signaling Pathway

13.2K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the  phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

Phase Changes

4.7K
Phase transitions play an important theoretical and practical role in the study of heat flow. In melting or fusion, a solid turns into a liquid; the opposite process is freezing. In evaporation, a liquid turns into a gas; the opposite process is condensation.
A substance melts or freezes at a temperature called its melting point and boils or condenses at its boiling point. These temperatures depend on pressure. High pressure favors the denser form of the substance, so typically, high pressure...

The ADP/ATP Carrier Protein01:42

The ADP/ATP Carrier Protein

3.6K
ADP/ATP carrier or AAC protein is the most abundant carrier protein in the inner mitochondrial membrane. It transports large quantities of ADP and ATP, equivalent to the average human body weight, every day. Among other transporters, ACC protein is one of the best-studied members of the mitochondrial carrier protein family. The ADP/ATP carrier protein comprises two transmembrane helices connected to a loop and a single alpha-helix on the matrix side. It switches between two conformational...

Membrane Domains01:18

Membrane Domains

6.4K
The membrane domains concentrate specific lipids and proteins at one place within the membrane, which helps in cell signaling, adhesion, and other critical cellular processes. These domains can differ in size, composition, function, and lifespan.
Protein Domains
The membrane comprises a group of distinct proteins responsible for carrying out a cell's specific function. For example, the plasma membrane of the human sperm, or a single germ cell, contains a unique set of proteins in the...

Anaphase Promoting Complex00:50

Anaphase Promoting Complex

3.0K
The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...

Area of Science:

  • Genomics
  • Proteomics
  • Bioinformatics

Background:

  • Alternative splicing generates multiple mRNA transcripts from a single gene, potentially leading to protein isoforms with varying domain compositions.
  • Manually analyzing alternative splicing's effect on protein domains is complex, error-prone, and impractical for large-scale studies.

Purpose of the Study:

  • To develop an automated, user-friendly web server for visualizing exon-domain associations.
  • To facilitate the study of alternative splicing's structural impact on protein domains at a genome-wide scale.

Main Methods:

  • Development of the Domain Change Presenter (DoChaP) web server.
  • Visualization of gene transcripts, encoded proteins, and their domain structures.
  • Inclusion of comparative analysis between transcripts and protein products.
  • Implementation of a two-species comparison for exon-domain association conservation.

Main Results:

  • DoChaP provides intuitive visualization of how alternative splicing events alter protein domain composition.
  • The tool enables easy identification of structural changes in proteins due to splicing variations.
  • DoChaP supports the study of exon structure and alternative splicing conservation across species.

Conclusions:

  • DoChaP offers a unique and accessible platform for exploring exon-domain associations and their conservation.
  • The tool simplifies the investigation of alternative splicing's structural consequences in biological contexts, including disease states.
