Cytoglobin function

WebCytoglobin, a novel member of the globin family, protects kidney fibroblasts against oxidative stress under ischemic conditions Cytoglobin (Cygb) is a novel member of the vertebrate globin superfamily. Although it is expressed in splanchnic fibroblasts of various organs, details of its function remain unknown. WebApr 18, 2024 · Although conserved in most vertebrates, the function of cytoglobin is yet unknown. The changes in heme coordination lead to properties not consistent with an oxygen transport role, and a number of functions such as scavenging of reactive oxygen species, nitrite reduction, and nitric oxide dioxygenation have been proposed.
