Recombinant proteins are gaining popularity due to their pivotal role as essential components in biological systems, facilitating numerous vital processes within cells. These processes encompass gene expression, proliferation, cell growth, nutrient uptake, apoptosis, and intercellular communication.
Understanding Recombinant Proteins
Recombinant proteins refer to proteins that are formed within a host by introducing foreign genes into them through transfection. These proteins represent a novel combination of genes, constituting the DNA. They are constructed from cloned DNA sequences that encode enzymes or proteins.
Recombinant proteins can be modified to produce pharmaceutical products and other enzymes. They can also be engineered into antibodies for disease treatment and utilized as protein-based polymers for drug delivery. The applications of recombinant proteins extend significantly into tissue engineering and various medical engineering fields.
Latest Updates on Recombinant Proteins
The usage of recombinant proteins is widespread across academic research institutes, pharmaceutical and biopharmaceutical companies, biotechnology companies, and contract research organizations. However, pharmaceutical and biopharmaceutical companies stand as the largest consumers of recombinant proteins, mainly due to their increasing adoption by major manufacturers in drug discovery and target detection efforts.
Moreover, the rising prevalence of various rare disorders, such as neutropenia, multiple sclerosis, cerebral apoplexy, dwarfism, and anemia, is driving the demand for drugs based on recombinant proteins. These agents are also instrumental in developing novel therapies for severe chronic disorders, including cardiovascular diseases, cancer, viral diseases, and endocrine diseases.
The growing occurrence of such conditions is expected to fuel the need for recombinant protein drugs in the years to come.
Furthermore, advancements in technology are contributing to the expansion of the recombinant proteins industry with various methods being developed for synthesizing these proteins. These advancements include the production of alternative cell lines and enhanced cell culture techniques, along with the introduction of new expression technologies like baculovirus expression, E. coli expression, and mammalian cell expression. These innovations have streamlined and facilitated the production of recombinant proteins.
Increasing Use of Growth Factors and Chemokines
Among various types of recombinant proteins, growth factors, and chemokines are experiencing significant utilization, particularly in research studies focusing on neurobiology, immunology, COVID-19, cancer, and HIV/AIDS. Growth factors and chemokines are signaling molecules that control the activity of cells in an endocrine, paracrine, or autocrine manner. They bind to receptors, initiating downstream signaling pathways that influence gene transcription within the nucleus, ultimately leading to biological responses.
Widespread Use of Recombinant Proteins in Biologics
The most widespread use of recombinant proteins in the field of drug discovery and development, particularly in biologics. The increasing inclination of biopharma and pharma firms to expand their research and development efforts and product pipelines for biologics and biosimilars, coupled with advancements in bioprocessing science and novel technologies, has driven this growth.
Moreover, the rising demand for biopharmaceuticals and their expanding applications, as well as intensified competition among major companies, further contribute to the prominence of recombinant proteins.
With the prevalence of chronic disorders increasing in emerging economies such as China and India, and substantial public and private funding being directed towards recombinant protein research and development across Asian nations, the demand for recombinant proteins will keep rising, and it will reach a value of USD 3,203.7 million by the end of this decade.
