Cytoglobin bonds
Cytoglobin is the protein product of CYGB, a human and mammalian gene. Cytoglobin is a globin molecule ubiquitously expressed in all tissues and most notably utilized in marine mammals. It was discovered in 2001 and named cytoglobin in 2002. It is thought to protect against hypoxia. The predicted function of … See more Cytoglobin is a ubiquitously expressed hexacoordinate hemoglobin that may facilitate diffusion of oxygen through tissues, scavenge nitric oxide or reactive oxygen species, or serve a protective function during See more CYGB expression can be used as a specific marker with which hepatic stellate cells can be distinguished from portal myofibroblasts in … See more • cytoglobin at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more • Kawada N, Kristensen DB, Asahina K, Nakatani K, Minamiyama Y, Seki S, Yoshizato K (Jul 2001).
