FCER1
FCER1
FCER1 (pronounced as F-C-E-R-One), also known as High Affinity Immunoglobulin Epsilon Receptor Subunit Alpha, is a protein that in humans is encoded by the FCER1A gene.
Etymology
The term FCER1 is an abbreviation for Fc Epsilon Receptor 1. The Fc part of the name refers to the Fragment crystallizable region of an antibody, epsilon (ε) refers to the type of antibody (IgE), and receptor indicates that it binds to a specific substance.
Function
FCER1 is a receptor that binds to the Fc region of immunoglobulin E (IgE), a type of antibody. This binding is a crucial part of the immune response, particularly in allergic reactions. The FCER1 receptor is found on the surface of certain immune cells, including mast cells and basophils.
