What is the official name of the PDGFRB gene?
The official name of this gene is “platelet derived growth factor receptor beta.”
PDGFRB is the gene's official symbol. The PDGFRB gene is also known by other names, listed below.

What is the normal function of the PDGFRB gene?
The PDGFRB gene provides instructions for making a protein called platelet-derived growth factor receptor beta (PDGFRβ), which is part of a family of proteins called receptor tyrosine kinases. Receptor tyrosine kinases transmit signals from the cell surface into the cell through a process called signal transduction. The PDGFRβ protein is found in the cell membrane of certain cell types, where a protein called platelet-derived growth factor attaches (binds) to it. This binding turns on (activates) the PDGFRβ protein, which then activates other proteins inside the cell by adding a cluster of oxygen and phosphorus atoms (a phosphate group) at specific positions. This process, called phosphorylation, leads to the activation of a series of proteins in multiple signaling pathways.
The signaling pathways stimulated by the PDGFRβ protein control many important processes in the cell such as growth and division (proliferation), movement, and survival. PDGFRβ protein signaling is important for the development of many types of cells throughout the body.
Does the PDGFRB gene share characteristics with other genes?
The PDGFRB gene belongs to a family of genes called immunoglobulin superfamily, immunoglobulin-like domain containing (immunoglobulin superfamily, immunoglobulin-like domain containing). It also belongs to a family of genes called immunoglobulin superfamily, I-set domain containing (immunoglobulin superfamily, I-set domain containing).
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.
