RESEARCH: CANCER
FOLDING PROJECT #16468 PROFILE

Cancer drugs often target kinases like RIPK2. The project simulates RIPK2 with 3 known inhibitors to understand how they stop RIPK2 from binding to another protein (XIAP), which is important for cancer growth. This will help develop better cancer drugs and reveal how RIPK2 normally binds XIAP.

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 to other molecules.

Kinases are a type of enzyme crucial for many cellular processes. They add phosphate groups to other proteins, changing their activity and function. This process is essential for cell signaling, growth, and division. Dysregulation of kinases can lead to diseases like cancer.

Cancer

Uncontrolled growth and spread of abnormal cells.

Cancer is a broad term for diseases involving the uncontrolled growth and spread of abnormal cells. These cells divide rapidly and can invade surrounding tissues, potentially spreading to other parts of the body (metastasis). There are many types of cancer, each with unique characteristics and treatments.

Inhibitors

Substances that block or reduce the activity of a specific molecule.

Inhibitors are molecules designed to interfere with the function of other molecules, often enzymes. They can be used as drugs to treat diseases by blocking harmful processes. Examples include enzyme inhibitors used in cancer therapy.

RIPK2

Receptor-interacting protein kinase 2

RIPK2 is a protein involved in cell signaling pathways that regulate inflammation and cell death. It plays a role in the immune response and has been implicated in various diseases, including cancer.

XIAP

X-linked inhibitor of apoptosis protein

XIAP is a protein that inhibits cell death (apoptosis). It plays a role in protecting cells from damage and preventing excessive immune responses.
