RESEARCH: PLASMEPSIN-II
FOLDING PROJECT #17260 PROFILE

This project uses computer models to find hidden spots on a malaria parasite protein that drugs could latch onto. By studying how the protein moves, they hope to discover new ways to fight malaria.

Note: This TLDR is a simplication and may not be 100% accurate.

Identification of drug binding pockets is crucial for drug discovery research.

Drug binding pockets often remain hidden in the experimentally determined structures.

Protein dynamics can reveal protein confomrations that expose such drug binding pockets in some of the high-energy states that remain unidentified by experimental techniques.

Here, we combine the power of alpha-fold and molecular dynamics simulations to generate an ensemble of protein conformations to find drug binding pockets in plasmepsin-II protein from Plasmodium falciparum that degrades host haemoglobin.

drug binding pockets

Regions on a protein where drugs can bind.

Drug binding pockets are specific areas on proteins that drugs can attach to. This binding is crucial for medications to work because it allows them to interact with and influence the protein's function.

protein dynamics

The movement and flexibility of proteins.

Protein dynamics refers to the constant motion and changes in shape that proteins undergo. This flexibility is essential for proteins to perform their various functions, such as binding to other molecules or catalyzing chemical reactions.

alpha-fold

An AI system for predicting protein structures.

AlphaFold is a groundbreaking artificial intelligence program developed by DeepMind that can accurately predict the three-dimensional structure of proteins. This has revolutionized our understanding of protein function and has wide-ranging applications in drug discovery and disease research.

molecular dynamics simulations

Computer models that simulate the movement of atoms and molecules.

Molecular dynamics simulations are powerful computer programs that allow scientists to model the behavior of atoms and molecules over time. These simulations provide valuable insights into the dynamic processes occurring within biological systems, such as protein folding and drug binding.

plasmepsin-II

A protease enzyme found in Plasmodium falciparum.

Plasmepsin-II is a type of enzyme produced by the malaria parasite Plasmodium falciparum. It plays a crucial role in the parasite's survival by breaking down hemoglobin, the protein that carries oxygen in red blood cells.

Plasmodium falciparum

The parasite that causes the most severe form of malaria.

Plasmodium falciparum is a parasitic protozoan responsible for the deadliest type of malaria. It infects red blood cells and can lead to life-threatening complications if left untreated.

haemoglobin

The protein in red blood cells that carries oxygen.

Hemoglobin is a complex protein found within red blood cells. It has the crucial role of binding to oxygen in the lungs and transporting it throughout the body to deliver oxygen to tissues and organs.
