The SQSTM1 gene provides instructions for making a protein called sequestosome-1. This protein helps regulate bone remodeling, a normal process in which old bone is broken down and replaced by new bone. Sequestosome-1 is involved in a chemical signaling pathway that promotes the formation and activity of bone cells called osteoclasts, which are specialized cells that break down bone tissue during bone remodeling.
Normal function
The SQSTM1 gene provides instructions for making a protein called sequestosome-1. This protein helps regulate bone remodeling, a normal process in which old bone is broken down and replaced by new bone. Sequestosome-1 is involved in a chemical signaling pathway that promotes the formation and activity of bone cells called osteoclasts, which are specialized cells that break down bone tissue during bone remodeling.
In addition to its role in bone remodeling, sequestosome-1 may have other functions, although these are less well-defined. Sequestosome-1 may be involved in recycling worn-out cell parts and unneeded proteins (autophagy), the self-destruction of cells when they are no longer needed (apoptosis), and the body's immune responses and inflammatory reactions.
