What is the official name of the CLCF1 gene?
The official name of this gene is “cardiotrophin-like cytokine factor 1.”
CLCF1 is the gene's official symbol. The CLCF1 gene is also known by other names, listed below.

What is the normal function of the CLCF1 gene?
The CLCF1 gene provides instructions for making a protein called cardiotrophin-like cytokine factor 1 (CLCF1). This protein partners with a similar protein called cytokine receptor-like factor 1 (CRLF1), which is produced from the CRLF1 gene. Together, these two proteins form a unit known as the CRLF1/CLCF1 protein complex. This complex attaches (binds) to a receptor protein known as the ciliary neurotrophic factor receptor (CNTFR) on the surface of many types of cells. When the CRLF1/CLCF1 protein complex is bound to CNTFR, it triggers signaling inside the cell that affects cell development and function.
The CNTFR signaling pathway is primarily involved in the development and maintenance of the nervous system. It promotes the survival of nerve cells (neurons), particularly nerve cells that control muscle movement (motor neurons). The CNTFR pathway also plays a role in a part of the nervous system called the sympathetic nervous system, specifically in the regulation of sweating in response to temperature changes and other factors. This signaling pathway appears to be critical for the normal development and maturation of nerve cells that control the activity of sweat glands.
Studies suggest that the CNTFR signaling pathway also has functions outside the nervous system. It may be involved in the body's inflammatory response, which helps fight infection and facilitate tissue repair following an injury. This pathway may also be important for the development and maintenance of bone tissue. However, little is known about the role of CNTFR signaling in these processes.
