What is the official name of the BIN1 gene?
The official name of this gene is “bridging integrator 1.”
BIN1 is the gene's official symbol. The BIN1 gene is also known by other names, listed below.

What is the normal function of the BIN1 gene?
The BIN1 gene provides instructions for making a protein that is found in tissues throughout the body, where it interacts with a variety of other proteins. The BIN1 protein is thought to be involved in transporting materials from the cell surface into the cell (endocytosis) and the self-destruction of cells (apoptosis). The BIN1 protein may act as a tumor suppressor protein, which means it prevents cells from growing and dividing too rapidly or in an uncontrolled way.
Several different versions (isoforms) of the BIN1 protein are produced from the BIN1 gene. These isoforms vary by size and are active (expressed) in different tissues. The BIN1 protein isoform that is expressed in muscle cells is thought to be involved in the formation of cell membrane structures called transverse tubules or T tubules. These structures are found solely in the membranes of muscle cells, and they play a role in muscle tensing (contraction) and relaxation.
