Lysosomal desialylation is the initial step in the degradation of sialo-glycopeptides that is essential for regenerating sialo-glycoconjugates. Neu1 sialidase is the enzyme responsible for the removal of sialic acid in the mammalian lysosome. Although Neu1 sialidases are conserved in fish similar to mammals, their physiological functions remain to be fully understood. Nile tilapia (Oreochromis niloticus) is known to possess two putative Neu1 sialidases (Neu1a and Neu1b) in the genome that may have arisen by gene duplication (specific
