What is the normal function of the ANO5 gene?
The ANO5 gene provides instructions for making a protein called anoctamin 5. While the specific function of this protein is not well understood, it belongs to a family of proteins that are believed to function as calcium-activated chloride channels.
Chloride channels, which transport negatively charged chlorine atoms (chloride ions) in and out of cells, play a key role in a cell's ability to generate and transmit electrical signals. Studies suggest that the anoctamin proteins function as chloride channels that are turned on (activated) in the presence of positively charged calcium atoms (calcium ions), although the mechanism for this activation is not clear.
Chloride channels have many functions throughout the body. The anoctamin 5 protein is most abundant in muscles used for movement (skeletal muscles). For the body to move normally, skeletal muscles must tense (contract) and relax in a coordinated way. Muscle contraction and relaxation are controlled by the flow of certain ions into and out of muscle cells. Chloride channels spanning the muscle cell membrane control the flow of chloride ions into these cells.
The anoctamin 5 protein is also found in the muscle cells of the heart and in bone cells.
