**Background of MRJP1 Recombinant Protein**
MRJP1 (Major Royal Jelly Protein 1) is a key glycoprotein found in royal jelly, a secretion produced by honeybee workers to nourish queen larvae and adult queens. Constituting approximately 50% of royal jelly proteins, MRJP1 plays a vital role in the unique physiological and developmental traits of queen bees, including their extended lifespan and fertility. Structurally, MRJP1 is a 55 kDa protein characterized by its water-soluble, thermostable nature and a high proportion of essential amino acids. Its biological significance extends beyond insect biology, showing potential bioactivity in mammals, such as immunomodulatory, antimicrobial, and antioxidant properties.
The recombinant form of MRJP1 is produced using biotechnological platforms (e.g., bacterial, yeast, or insect cell expression systems) to overcome limitations in natural extraction, such as low yield and batch variability. Recombinant MRJP1 retains functional properties while enabling scalable, cost-effective production. Studies have highlighted its therapeutic potential, including wound healing, anti-aging effects, and neuroprotective roles. Additionally, its ability to stimulate cell proliferation and modulate immune responses has spurred interest in pharmaceutical and cosmetic applications.
Recent research also explores MRJP1’s role in mammalian cell signaling pathways, such as activating EGFR or enhancing collagen synthesis. However, challenges remain, including optimizing post-translational modifications (e.g., glycosylation) to ensure bioactivity and addressing allergenicity concerns. Despite these hurdles, MRJP1 recombinant protein represents a promising biomolecule bridging apiculture, biotechnology, and biomedical innovation, with ongoing studies aiming to unlock its full therapeutic and commercial potential.
