What is the official name of the RBPJ gene?
The official name of this gene is “recombination signal binding protein for immunoglobulin kappa J region.”
RBPJ is the gene's official symbol. The RBPJ gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the RBPJ gene?
The RBPJ gene provides instructions for making a protein called RBP-J, which is an integral part of a signaling pathway known as the Notch pathway. Notch signaling controls how certain types of cells develop in the growing embryo, including those that form the bones, heart, muscles, nerves, and blood. Signaling through the Notch pathway stimulates the RBP-J protein to attach (bind) to specific regions of DNA and control the activity of genes that play a role in cellular development.
How are changes in the RBPJ gene related to health conditions?
Genetics Home Reference provides information about rheumatoid arthritis, which is also associated with changes in the RBPJ gene.
Where is the RBPJ gene located?
Cytogenetic Location: 4p15.2
Molecular Location on chromosome 4: base pairs 26,163,493 to 26,435,130
The RBPJ gene is located on the short (p) arm of chromosome 4 at position 15.2.
More precisely, the RBPJ gene is located from base pair 26,163,493 to base pair 26,435,130 on chromosome 4.
