“Cellular Proteins”  

Cellular Protein

  In our body's cells, Cellular Proteins, and protein-containing complexes, are the chief actors that carrying out the duties specified by the information encoded in our genes, that vary widely depending on the type of cell and related tissues.
  Examples of cellular proteins include:

• endosomal proteins
• sirtuin proteins (SIRT proteins)

“Mitochondrial Proteins”  

Mitochondrion Protein

  In the mitochondria of our body's cells, Mitochondrial Proteins are cellular proteins that vary widely depending on the type of cell and related tissues.
  In our body,s heart, 615 distinct types of Mitochondrion Proteins have been identified in the cardiac mitochondria. **

“Thioredoxins”  

Thioredoxin

  In our body's cells, Thioredoxins are hydrogen-donating cellular protein enzymes, that act as antioxidants by facilitating the reduction of other proteins. Thioredoxin is encoded by the TXN Gene.
  In our body's cells, Thioredoxins participates in a variety of biochemical reactions including ribonucleotide reduction and reduction of peroxiredoxins, thioredoxin is oxidized from a dithiol to a disulfide when acting as a reducing cofactor, the disulfide form gets reduced by NADPH in a reaction catalyzed by thioredoxin reductase.
  Examples of thioredoxins include:

• Chloroplast Thioredoxins
• Thioredoxin h

“Actins (ACT Gene Family)”  

Actins

  In our body, Actins, as a muscle proteins, are filamentous proteins that are the main constituent of the thin filaments of muscle fibers. The filaments (known also as filamentous or F-actin) can be dissociated into their globular subunits; each subunit is composed of a single polypeptide 375 amino acids long. This is known as globular or G-actin.
  In our body, Actins in conjunction with myosins, are responsible for the contraction and relaxation of muscle.

In our body's muscular system, Actin is the protein which microfilaments are composed of forming the contractile filaments of sarcomeres in muscle cells.
  This gene family contains the following genes:

• ACTA1 gene (actin, alpha 1, skeletal muscle)
• ACTA2 gene (actin, alpha 2, smooth muscle, aorta)
• ACTB gene (actin beta)
• ACTC1 gene (actin, alpha, cardiac muscle 1)
• ACTG1 gene (actin gamma 1)
• ACTG2 gene (ACTSG gene) (actin, gamma 2, smooth muscle, enteric)

“Acute-Phase Proteins”  

  In our body, Acute-Phase Proteins are blood proteins (plasma proteins) that are secreted into the blood in increased or decreased quantities by hepatocytes (hepatocyte cells) in response to trauma, inflammation, or dis-ease.
  Examples of some acute-phase proteins include:

• alpha 1-Antichymotrypsin
• alpha 1-antitrypsin
• alpha-Macroglobulins
• C-Reactive Protein
• Ceruloplasmin
• Complement C3
• Fibrinogen
• Haptoglobins
• Hemopexin
• orosomucoids
  • Alpha-1-acid glycoprotein (AGP), also known as orosmucoid-1
    • AGP1 encoded by ORM1
    • AGP2 encoded by ORM2
• Serum Albumin
• serum amyloid A protein
• serum amyloid p-component
• Transferrin
• Kazal Pancreatic Trypsin Inhibitor

“Acyl Carrier Proteins”  

Acyl Carrier Protein

  Important in lipid science, Acyl Carrier Protein is a transport protein consisting of a polypeptide chain and 4'-phosphopantetheine linked to a serine residue by a phosphodiester bond.
  In our body, Acyl Carrier Proteins are involved in every step of fatty acid synthesis by the cytoplasmic system. **
