What is the official name of the EPOR gene?
The official name of this gene is “erythropoietin receptor.”
EPOR is the gene's official symbol. The EPOR gene is also known by other names, listed below.

What is the normal function of the EPOR gene?
The EPOR gene provides instructions for making a protein called the erythropoietin receptor. Erythropoietin is a hormone that directs the production of new red blood cells (erythrocytes) in the bone marrow. Red blood cells make up about half of total blood volume, and their primary function is to carry oxygen from the lungs to tissues and organs throughout the body. New red blood cells are constantly being produced by the body as worn-out red blood cells are broken down. To trigger the production of red blood cells, erythropoietin attaches (binds) to the erythropoietin receptor. This binding turns on (activates) the receptor, which stimulates several signaling pathways (particularly a cascade of signals known as the JAK/STAT pathway) that lead to the formation and maturation of red blood cells.
Does the EPOR gene share characteristics with other genes?
The EPOR gene belongs to a family of genes called fibronectin type III domain containing (fibronectin type III 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.

Where is the EPOR gene located?
Cytogenetic Location: 19p13.3-p13.2
Molecular Location on chromosome 19: base pairs 11,377,204 to 11,384,341
The EPOR gene is located on the short (p) arm of chromosome 19 between positions 13.3 and 13.2.
More precisely, the EPOR gene is located from base pair 11,377,204 to base pair 11,384,341 on chromosome 19.
