Globular Proteins01:27

Globular Proteins

9.1K
In organisms, proteins are the most abundant macromolecules. They act as the building blocks of life and play various crucial roles in the body. Proteins can be broadly classified into two distinct subtypes based on their shape and solubilities: globular proteins and fibrous proteins.
Globular proteins serve many important physiological functions, such as acting as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be soluble in the aqueous...

Gene Families01:57

Gene Families

9.3K
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Globular and Fibrous Proteins02:21

Globular and Fibrous Proteins

45.2K
Many proteins can be classified into two distinct subtypes - globular or fibrous. These two types differ in their shapes and solubilities.
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...

Hemoglobin01:24

Hemoglobin

5.5K
Hemoglobin is a globular protein made up of four subunits. Two of these subunits are alpha chains, and the other two are beta chains. Each subunit contains a molecule of heme, which has an iron atom and can bind to oxygen. When an oxygen molecule binds to one heme group, it changes the shape of hemoglobin, making it easier for the other heme groups to bind oxygen as well.
When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...

Structure and Function of Erythrocytes01:29

Structure and Function of Erythrocytes

3.1K
There are between 4.2 and 6 million erythrocytes, also known as red blood cells, in every microliter of blood. These cells are small, flattened biconcave discs with centers that are depressed.
The erythrocyte plasma membrane is associated with proteins such as spectrin, which forms a flexible cytoplasmic meshwork. This meshwork allows erythrocytes to twist, turn, become cup-shaped, and regain their biconcave shape as they pass through narrow capillaries. Additionally, erythrocytes can form...

Area of Science:

  • Neuroscience
  • Biochemistry
  • Evolutionary Biology

Background:

  • Neuroglobin is an evolutionarily ancient globin family member found in vertebrate brains.
  • Its presence in nervous cells suggests a critical role in the central nervous system.
  • Despite evidence for neuroglobin's involvement in neuron viability, its precise function is still debated.

Purpose of the Study:

  • To review recent findings on neuroglobin's function.
  • To synthesize data from biochemical, biophysical, structural, cellular, and in vivo studies.
  • To provide an overview of current hypotheses regarding neuroglobin's roles.

Main Methods:

  • Literature review integrating diverse experimental approaches.
  • Analysis of biochemical, biophysical, and structural data.
  • Consideration of in vitro and in vivo experimental findings.

Main Results:

  • Neuroglobin is implicated in sustaining neuron viability under various conditions.
  • Its complex role may involve multiple functions within the central nervous system.
  • Evidence suggests neuroglobin might have evolved multiple "jobs" to ensure nervous system function.

Conclusions:

  • The precise biochemical role and mechanism of neuroglobin are not fully elucidated.
  • Understanding neuroglobin requires integrating data from multiple scientific disciplines.
  • Neuroglobin likely plays a multifaceted role in supporting the demanding vertebrate nervous system.
