"Hemoglobin protein" refers to a type of protein in our blood that helps carry oxygen to different parts of our body. It's an essential component that ensures our organs and tissues get the oxygen they need to function properly.
Full definition
After comparing the ancestral vs.
modern hemoglobin proteins of nine species that inhabit the Tibetan Plateau, the team did identify two cases in which distantly related species underwent identical, functionally important mutations.
Blood tests didn't turn up any evidence of
damaged hemoglobin proteins but did find some evidence that oil - sipping birds might be anemic, Goodchild said.
For the discovery reported in Science, the researchers used a technique called «protein engineering» to
synthesize hemoglobin proteins that contained each of the naturally occurring mutations in all possible multi-site combinations.
If an overly high percentage of
our hemoglobin proteins begin to take this form, healthcare providers begin to suspect problems in glucose and insulin metabolism.
Earlier research by Storz's group on populations of North American deer mice that are native to high and low altitudes had found that the high - altitude mice had evolved hemoglobins with an increased oxygen - binding affinity — and that this difference is attributable to the combined effects of genetic mutations at 12 different sites in
the hemoglobin protein.
They inherit a mutation that affects
the hemoglobin protein that red blood cells use to ferry oxygen throughout the body.
What's more, inherited diseases can arise from a problem with one gene (a simple example is sickle - cell anemia, a condition caused by defects in a single gene that makes
the hemoglobin protein), or from interactions among a range of genetic variations as well as, frequently, environmental stresses.
In these patients,
the hemoglobin protein present inside the red blood cells is abnormal, causing the RBCs to become rigid, sticky and «C» or... -LSB-...]
