What Are Recombinant Proteins & Why They Are So Important?

Proteins are the workhorses of organic systems, assisting the bulk of organic techniques in a cell including gene expression, cell growth, proliferation, vitamins uptake, intercellular communication, and apoptosis. They also help in increasing muscle mass and strengthening bones, while improving sleep and brain health.

When it comes to a molecule of protein, it is made up of 20 different amino acids. These amino acids are split into 2 categories: Non-Essential Amino Acids and Essential Amino Acids (EAAs)

Non-Essential Amino Acids – produced within the body naturally.

Essential Amino Acids – not produced within the body naturally and must be consumed through food or supplementation.

In this article, we try to explain the recombinant proteins to help you understand what it is, why it is important, and why do we need it.

What exactly are recombinant proteins?

Recombinant proteins are proteins that are encoded via way of means of recombinant DNA that has been cloned in an expression vector that helps gene expression and messenger RNA translation.

In the pursuit of modifying the gene, the application of recombinant DNA technology can result in the production of a mutant protein. A recombinant protein is an altered form of a native protein that is produced in a variety of ways to increase protein production, alter gene sequences, and produce commercially useful products.

The genetic level of recombinant protein production begins with the isolation and cloning process. This happens in the coding sequence for the protein of interest into an expression plasmid vector. Largely, the recombinant proteins used in medicine are procured from humans. However, they are expressed in microorganisms like yeast, bacteria, or animal cells in culture.

The economic efficiency, simplicity, and speed of the process, together with constant product yield, facilitate the production of recombinant proteins for research purposes.

Why do we need recombinant proteins?

  1. Biomedical Research

Recombinant proteins can help researchers with the enhanced understanding of protein-protein interactions. Recombinant Protein microarrays for studying protein-protein interactions have recently become popular for studying how two agents interact with each other.

Recombinant proteins have been shown to be effective in a variety of scientific methods, including ELISA, Western blotting, and immunohistochemistry (IHC). Enzymatic tests are created using recombinant protein. Recombinant proteins are also used as measuring standards in ELISA as well as IHC when used together with a matching antibody pair.

Recombinant proteins are quite helpful in studying and understanding the biological response to stress and disease. Researchers can find possible new treatment options using recombinant proteins and peptides in animal models of disease.

  1. Biotherapeutic Recombinant Proteins

The majority of human disorders are broadly connected to the malfunction of protein in the body. Therapeutic proteins are important in the treatment of various diseases such as diabetes, cancer, infectious diseases, haemophilia, and anaemia. Antibodies, Fc fusion proteins, hormones, interleukins, enzymes, and anticoagulants are examples of common therapeutic proteins.

The Hepatitis B vaccine is one of the multiple RP vaccines licensed by the FDA for the protection of infection caused by all known subtypes of the Hepatitis B virus. Recombinant proteins are effective medications with having fewer side effects and a lesser time of development than small compounds.

Recombinant proteins clinic includes recombinant hormones, interferons, interleukins, growth factors, tumour necrosis factors, blood clotting factors, thrombolytic drugs, and enzymes used to treat major diseases such as diabetes, dwarfism, congestive heart failure, cerebral apoplexy, thrombocytopenia, anaemia, neutropenia, hepatitis, and multiple sclerosis.

  1. Animal Husbandry

Recombinant proteins can be added to animal feed to increase the nutritional value of feed ingredients, reduce feed costs and waste disposal, improve animal gastrointestinal health and improve livestock productivity, and improve the livestock environment.

Technologies that have made it possible to produce a wide variety of proteins are of interest, including those used in animal husbandry. The proteins most studied for animal husbandry are those that play an important role in reproduction, feed efficiency, and health; however, despite significant advances in reducing the cost of protein production, alternative strategies are still required to further reduce these costs.

In this context, a leap towards the use of new strategies such as nanotechnology is needed, which, in combination with recombinant technology, will make recombinant molecules affordable for the livestock industry.


Advances in biotechnology have boosted and facilitated the production of recombinant proteins for a variety of purposes. The cost of recombinant proteins in simple existence technology research, diagnostic reagents, and medicinal drugs have grown dramatically.

The significance of recombinant proteins in biotechnology can’t be overstated. We additionally desire to look at more advances withinside the use of recombinant proteins withinside the remedy of diverse ailments.

Recombinant DNA generation permits modulating protein sequence, which consequently makes it viable to reap recombinant merchandise with stepped forward homes as compared with the ones remoted from their local hosts.
