RESEARCH: CANCER
FOLDING PROJECT #16466 PROFILE

Kinases are important targets for cancer drugs, but we don't fully understand how they work. The project focuses on RIPK2, a kinase involved in cancer. Scientists are using computer models to study how three known RIPK2 inhibitors block its interaction with another protein called XIAP. This research could lead to better cancer treatments and reveal how RIPK2 binds to XIAP in the first place.

Kinases are a major target for a variety of cancer therapies, but their mechanism of action is relatively unknown at a detailed atomic level, preventing us from understanding and optimizing known inhibitors.

One example is the Serine/Threonine Kinase RIPK2.

RIPK2 inhibition is useful for cancer targeting as it prevents RIPK2 from binding a protein partner named XIAP.

In fact, there are already 3 known inhibitors that bind to RIPK2 and prevent RIPK2-XIAP binding! However, it remains difficult to optimize these ligands for clinical purposes because we do not understand how any of these three inhibitors actually act on RIPK2 to prevent XIAP binding behavior.

These four projects are simulating RIPK2 by itself and bound to each of the three inhibitors, with the hope that this will reveal a more detailed mechanism of how each inhibitor works to prevent XIAP binding.

As a bonus, this will help reveal how RIPK2 *binds* XIAP (also unknown)!.

Kinases

Enzymes that transfer phosphate groups from ATP to other molecules.

Kinases are a type of enzyme crucial for cell signaling and regulation. They play diverse roles in processes like growth, differentiation, and metabolism. Dysregulation of kinases is implicated in various diseases, including cancer.

RIPK2

Receptor-interacting protein kinase 2

RIPK2 is a protein involved in the innate immune response. It plays a role in detecting pathogens and triggering inflammatory responses. Its dysregulation can contribute to autoimmune diseases and cancer.

Inhibitors

Substances that block or reduce the activity of a specific molecule, such as an enzyme.

Inhibitors are crucial in drug development. They aim to block the action of harmful molecules involved in diseases. By targeting specific enzymes or proteins, inhibitors can help treat various conditions.

XIAP

X-linked inhibitor of apoptosis protein

XIAP is a protein that inhibits programmed cell death (apoptosis). It plays a role in regulating cell survival and immune responses. Its overexpression can contribute to cancer development.
