the enzyme is expressed in two distinct phases during the zebrafish embryogenesis. The early phase extends from late blastulation to the completion of epiboly, during which the expression occurs in the superficial layer of the embryos. The second phase of expression starts during mid-segmentation and persists until day 3, during which the expression occurs prominently in the developing lens. Hedgehog signaling is required for the Lc3 synthase expression in embryonic lens

the enzyme is expressedin two distinct phases during the zebrafish embryogenesis. The early phase extends from late blastulation to the completion of epiboly, during which the expression occurs in the superficial layer of the embryos. The second phase of expression starts during mid-segmentation and persists until day 3, during which the expression occurs prominently in the developing lens. Hedgehog signaling is required for the Lc3 synthase expression in embryonic lens

multiple phenotypic changes in mice after knockout of the B3gnt5 gene, encoding Lc3 synthase, detailed overview. B3gnt5 gene knockout mutant mice appear normal in the embryonic stage and, if they survive delivery, remain normal during early life, but about 9% develop early-stage growth retardation, 11% die postnatally in less than 2 months, and adults tend to die in 5-15 months, demonstrating splenomegaly and notably enlarged lymph nodes. Without lacto-neolacto series gangliosides, both homozygous and heterozygous mice gradually display fur loss or obesity, and breeding mice demonstrate reproductive defects. B3gnt5 gene knockout disrupts the functional integrity of B cells with a decrease in B-cell numbers in the spleen, germinal center disappearance, and less efficiency to proliferate in hybridoma fusion
