Endothelin receptor type B
Endothelin receptor type B, also known as ETB is a protein that in humans is encoded by the EDNRB gene.[1]
Function
Endothelin receptor type B is a G protein-coupled receptor which activates a phosphatidylinositol-calcium second messenger system. Its ligand, endothelin, consists of a family of three potent vasoactive peptides: ET1, ET2, and ET3. A splice variant, named SVR, has been described; the sequence of the ETB-SVR receptor is identical to ETRB except for the intracellular C-terminal domain. While both splice variants bind ET1, they exhibit different responses upon binding which suggests that they may be functionally distinct.[2]
Regulation
In melanocytic cells the EDNRB gene is regulated by the microphthalmia-associated transcription factor. Mutations in either gene are links to Waardenburg syndrome.[3][4]
Clinical significance
The multigenic disorder, Hirschsprung disease type 2, is due to mutation in endothelin receptor type B gene.[5]
Animals
In horses, a mutation in the middle of the EDNRB gene, Ile118Lys, when homozygous, causes Lethal White Syndrome.[6] In this mutation, a mismatch in the DNA replication causes isoleucine to be made instead of lysine.[6] The resulting EDNRB protein is unable to fulfill its role in the development of the embryo, limiting the migration of the melanocyte and enteric neuron precursors. A single copy of the EDNRB mutation, the heterozygous state, produces an identifiable and completely benign spotted coat color called frame overo.[7]
Interactions
Endothelin receptor type B has been shown to interact with Caveolin 1.[8]
