What is the function of Neuroglobin?

What is the function of Neuroglobin?

Neuroglobin is a protein found in neurons of both the peripheral and central nervous system that appears to convey some resilience to hypoxic/ischemic insult, perhaps by facilitating oxygen transport across the blood–brain barrier or enhancing availability of oxygen to mitochondria (Chuang et al., 2010).

Who discovered Neuroglobin?

Thorsten Burmester et
Neuroglobin was first identified by Thorsten Burmester et al. in 2000. The 3D structure of human neuroglobin was determined in 2003.

Is Neuroglobin a heme protein?

Neuroglobin (Ngb), a globular heme protein expressed in the brain of vertebrates, binds oxygen reversibly, with an affinity comparable to myoglobin (Mb).

What is globin chain?

The globins are a superfamily of heme-containing globular proteins, involved in binding and/or transporting oxygen. These proteins all incorporate the globin fold, a series of eight alpha helical segments. Two prominent members include myoglobin and hemoglobin.

Do humans have Neuroglobin?

In 2000, the third member of the globin family was discovered in human and mouse brain and named neuroglobin (Ngb). Ngb is a monomeric 3/3 globin structurally similar to myoglobin and to the α- and β-chains of hemoglobin, however it displays a bis-histidyl six-coordinate heme-Fe atom.

Who discovered myoglobin?

John Kendrew
Myoglobin was the first protein to have its three-dimensional structure revealed by X-ray crystallography. This achievement was reported in 1958 by John Kendrew and associates. For this discovery, Kendrew shared the 1962 Nobel Prize in chemistry with Max Perutz.

How many heme groups are there in myoglobin?

one heme group
Myoglobin is an oxygen-binding protein located primarily in muscles. It contains one heme group per molecule and has a structure similar to that of hemoglobin monomers.

Where is globin synthesized?

Hemoglobin synthesis occurs in the anucleate reticulocyte, however, on residual polyribosomes.

How is globin synthesized?

Normal α-globin synthesis is regulated by duplicate α-globin genes on chromosome 16. The genotype is usually represented as αα/αα and α-thalassaemia usually results from deletion of one or both α-genes. Occasionally point mutations in critical regions of the α-genes may cause non-deletional α-thalassaemia (αT).
