[Major royal jelly protein 1]: Most abundant protein component of royal jelly, a substance produced in the hypopharyngeal gland containing proteins, free amino acids, fatty acids, sugars and other nutrients, which is fed to developing larvae by worker nurse bees . Major royal jelly proteins (Mrjps) are high in essential amino acids and probably have a nutritional function in larval food . All larvae are fed some royal jelly (also known as worker jelly) early in their development but it forms the principal source of nutrition for larvae destined to become queen bees (Probable). Induces the differentiation of honey bee larvae into queens through an Egfr-mediated signaling pathway . Promotes body size increase by activating p70 S6 kinase, stimulates ovary development by augmenting the titer of vitellogenin (Vg) and juvenile hormone, and reduces developmental time by increasing the activity of mitogen-activated protein kinase and inducing 20-hydroxyecdysone (ecdysterone, 20E) production . Together with apisimin forms the apisin complex that polymerizes at low pH, forming a fiber network and increasing the viscosity of royal jelly . The viscous royal Jelly placed in honeycomb cells containing larvae destined to become queens acts as both a food supply and an adhesive preventing larvae from falling out; queens are reared in special large cells oriented vertically . Produced in the spermatheca of adult queen bees, along with other major royal jelly proteins, where it may act as a nutrient supply for sperm stored by mated queens, or be involved in energy metabolism . .; [Jellein-1]: Has antibacterial activity against the Gram-positive bacteria S.aureus ATCC 6535, S.saprophyticus and B.subtilis CCT2471, and the Gram-negative bacteria E.coli CCT1371, E.cloacae ATCC 23355, K.pneumoniae ATCC 13883 and P.aeruginosa ATCC 27853, and antifungal activity against C.albicans. Lack cytolytic activity and does not induce rat peritoneal mast cell degranulation. .; [Jellein-2]: Has antibacterial activity against the Gram-positive bacteria S.aureus ATCC 6535, S.saprophyticus and B.subtilis CCT2471, and the Gram-negative bacteria E.coli CCT1371, E.cloacae ATCC 23355, K.pneumoniae ATCC 13883 and P.aeruginosa ATCC 27853, and antifungal activity against C.albicans. Lack cytolytic activity and does not induce rat peritoneal mast cell degranulation. .; [Jellein-4]: Lacks antibacterial and antifungal activity. Lacks cytolytic activity and does not induce rat peritoneal mast cell degranulation. .
