Two human lysosomal membrane glycoproteins, h-lamp-1 and h-lamp-2, are encoded by genes localized to chromosome 13q34 and chromosome Xq24-25, respectively.
We have isolated previously cDNAs encoding two related human lysosomal membrane glycoproteins, h-lamp-1 and h-lamp-2 (Fukuda, M., Viitala, J., Matteson, J., and Carlsson, S.R. (1988) J. Biol. Chem. 263, 18920-18928). In the present study, we have determined the chromosomal localization of genes for h-lamp-1 and h-lamp-2. By using the method of in situ hybridization, we have localized the gene f...
متن کاملThe lysosomal membrane glycoproteins Lamp-1 and Lamp-2 are present in mobilizable organelles, but are absent from the azurophil granules of human neutrophils.
The subcellular localization of two members of a highly glycosylated protein group present in lysosomal membranes in most cells, the lysosome-associated membrane proteins 1 and 2 (Lamp-1 and Lamp-2), was examined in human neutrophil granulocytes. Antibodies that were raised against purified Lamp-1 adn Lamp-2 gave a distinct granular staining of the cytoplasm upon immunostaining of neutrophils. ...
متن کاملThe lysosomal polypeptide transporter TAPL is stabilized by interaction with LAMP-1 and LAMP-2.
TAPL (ABCB9) is a homodimeric polypeptide translocation machinery which transports cytosolic peptides into the lumen of lysosomes for degradation. Since the function of proteins is strongly dependent on the interaction network involved, we investigated the interactome of TAPL. A proteomic approach allowed identification of the lysosome-associated membrane proteins LAMP-1 and LAMP-2B as the most...
متن کاملThe lysosomal/phagosomal membrane protein h-lamp-1 is a target of the IgA1 protease of Neisseria gonorrhoeae.
Lysosomal/phagosomal membranes of mammalian cells are coated by highly conserved glycoproteins (lamps) that are thought to protect the membranes from degradation. Interestingly, we identified an amino acid sequence in human lamp-1 characteristic of a cleavage site for the Neisseria gonorrhoeae IgA1 protease. Furthermore, gonococci are detected in h-lamp-1-positive vacuoles after their uptake by...
متن کاملEvaluation of the lysosome-associated membrane protein LAMP-2 as a marker for lysosomal storage disorders.
For many lysosomal storage disorders, presymptomatic detection, before the onset of irreversible pathology, will greatly improve the efficacy of current and proposed therapies. In the absence of a family history, presymptomatic detection can be achieved only by a comprehensive newborn screening program. Recently we reported that the lysosome-associated membrane protein LAMP-1 was increased in t...
