What is the official name of the CSF1R gene?
The official name of this gene is “colony stimulating factor 1 receptor.”
CSF1R is the gene's official symbol. The CSF1R gene is also known by other names, listed below.

What is the normal function of the CSF1R gene?
The CSF1R gene provides instructions for making a protein called the colony stimulating factor 1 receptor (CSF-1 receptor). This protein is found in the outer membrane of certain cell types. When a specific protein called colony stimulating factor 1 attaches (binds) to it, the receptor turns on (activates) a series of proteins inside the cell that are part of multiple signaling pathways. The signaling pathways stimulated by the CSF-1 receptor control many important cellular processes such as cell growth and division (proliferation) and maturation of cells to take on specific functions (differentiation).
In the brain, the CSF-1 receptor is abundant in the membrane of specialized cells called glial cells. These cells protect and maintain nerve cells (neurons). The CSF-1 receptor is thought to be involved in the proliferation and differentiation of glial cells, but its exact role in the brain is unclear.
Does the CSF1R gene share characteristics with other genes?
The CSF1R gene belongs to a family of genes called CD (CD molecules).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
