| located in the outer membrane of the nuclear envelope ![](pubmed.jpg) |
|
localized to both the plasma membrane and the perinuclear region ![](pubmed.jpg) |
|
NEU1 and NEU3 are present on erythrocyte plasma membrane ![](pubmed.jpg) |
basic FUNCTION
| involved in stepwise degradation of complex type of oligosaccharide structure (glycoprotein catabolism), and cleavage of sialic acid from GM1 gangliosides |
|
upregulated during T cell activation |
|
can desialylate neighboring microfibrillar glycoproteins and facilitate the deposition of insoluble elastin, which contributes to the maintenance of cellular quiescence ![](pubmed.jpg) |
|
desialylates and functionally inactivates adjacent receptors interacting with the mitogenic growth factors PDGF-BB and IGF2 |
|
negatively regulates lysosomal exocytosis in hematopoietic cells by processing the sialic acids on the lysosomal membrane protein LAMP1 ![](pubmed.jpg) |
|
targeted to the cell surface in a multiprotein complex that facilitates elastic fiber assembly ![](pubmed.jpg) |
|
having a possible regulatory role in the early stages of myogenesis ![](pubmed.jpg) |
|
negative regulator of lysosomal exocytosis ![](pubmed.jpg) |
|
has been shown to regulate phagocytosis in macrophage cells ![](pubmed.jpg) |
|
NEU1 and MMP9 in complex with TLR receptors at the ectodomain form a molecular organizational signaling platform on the cell surface that is essential for ligand activation of TLR receptors and cellular signaling ![](pubmed.jpg) |
|
novel role as an intermediate in the initial process of ligand-induced TLR receptor activation and subsequent cellular signaling ![](pubmed.jpg) |
|
NEU1 restrains endothelial cell migration, whereas NEU3 does not ![](pubmed.jpg) |
|
its catalytic activity may offer an additional level of regulation over the airway epithelial response to ligands, pathogens, and injurious stimuli ![](pubmed.jpg) |
