What is the official name of the LRP5 gene?
The official name of this gene is “low density lipoprotein receptor-related protein 5.”
LRP5 is the gene's official symbol. The LRP5 gene is also known by other names, listed below.

What is the normal function of the LRP5 gene?
The LRP5 gene provides instructions for making a protein that is embedded in the outer membrane of many types of cells. It is known as a co-receptor because it works with another receptor protein, frizzled-4 (produced from the FZD4 gene), to transmit chemical signals from outside the cell to the cell's nucleus. Frizzled-4 and the LRP5 protein participate in the Wnt signaling pathway, a series of steps that affect the way cells and tissues develop. Wnt signaling is important for cell division (proliferation), attachment of cells to one another (adhesion), cell movement (migration), and many other cellular activities.
The LRP5 protein plays an important role in the development and maintenance of several tissues. During early development, it helps guide the specialization of cells in the retina, which is the light-sensitive tissue at the back of the eye. The LRP5 protein is also involved in establishing a blood supply to the retina and the inner ear. Additionally, this protein helps regulate bone mineral density, which is a measure of the amount of calcium and other minerals in bones. The minerals give the bones strength, making them less likely to break.
