We describe the isolation and sequencing of a cDNA encoding the mouse lysosomal membrane glycoprotein mLAMP-2 and the sequence differences that distinguish this molecule from the LAMP-1 class of proteins. An oligonucleotide probe corresponding to the NH2-terminal amino acid sequence of purified mLAMP-2 was synthesized by the polymerase chain reaction and used to screen several cDNA libraries. cDNA clones with an insert of 1,700 nucleotides were identified and sequenced. The deduced amino acid sequence of mLAMP-2 comprises a signal sequence of 25 residues and a 390-amino acid polypeptide (Mr 43,017) with the following putative domains: a large intraluminal region (residues 1-354) with 17 N-linked glycosylation sites (Asn-X-Ser/Thr), a hydrophobic transmembrane-spanning region of 24 residues (355-378), and a COOH-terminal cytoplasmic tail of 12 residues (379-390). When this sequence is compared with those of other lysosomal membrane glycoproteins, it is apparent that mouse LAMP-2 and human LAMP-2 form one homology class (LAMP-2) that is separated from the LAMP-1 class of proteins. The sequence differences in these two classes provide a basis for comparing the structure of the proteins with their biochemical and biological properties.
