Proteins, the bio-macromolecules, are complex high-order structures with various functionalities that deliver varied expressions. With the concept of recombinant protein, the varied expression of proteins is explained. The gene encoding and protein of interest into the host cell through a vector that can take over the host’s production of protein machinery.
Hence, the recombinant protein gave a breakthrough in being a major for a new era of genetic engineering capable enough to manipulate gene expression.
Challenges in Recombinant Protein Expression
It has excellent quality recombinant proteins that are compulsory for beginning materials to victory in research efforts and medicine development campaigns. The significant attributes that carry the quality parameter of the recombinant protein include purity, oligomeric states, thermo-chemical stability, folding, PTM (post-translational modification), activity. Because of the inherent complexity of proteins in general, expression protein and purification are often challenging. Some of the features within a protein can affect the stability of the recombinant protein product.
Solutions and Perspectives
1. Optimization Approach:
optimisation approaches usually require a systematic optimisation effort to formulate a workable procedure to express the high-quality protein.
2. Suitable Host:
host cells decide the potential folding and pattern of PTM (post-translational modification) of the recombinant protein.
3. vectors and Culture Condition:
vectors are the vehicle that delivers the aimed genes into a host cell.
4. Protein Constructs:
certain structural features on the aim protein may cause instability in the over-expressed form of a recombinant protein.
5. Purification Procedure:
proteins are sensible to their surrounding chemical environment change in ph, ionic strength; oxidation would impact protein stability.
Common Obstacles To Avoid
Usually, the protein of interest tends to express poorly due to toxicity in the host cells, insolubility, mRNA secondary structure that prevents interactions with the cellular machinery. At intervals, the genes of interest are rich in codons inconsistent with the host strains’ availability and supply of tRNAs. The uncontrolled basal expression can affect host cell growth and lower the protein yield. The history in recombinant protein expression has built a wide array of knowledge that serves as a primary source for the industry’s selling point.
Future of Protein Expression Techniques
the proteins which are present honestly have uncontrollable expression problems in a heterologous host. Still, protein expression techniques are presently expressing fast improvement with new evolution in tunable expression, solubility technology protein aiming, and cell-free system, broadly improving yield and purity over the expression system of only a few years ago
