A cDNA for 107 kDa sialoglycoprotein (LGP 107), the major protein component of rat liver lysosomal membranes, was isolated and sequenced. The 1.8 kbp cDNA contained an open reading frame encoding a polypeptide consisting of 386 amino acid residues (Mr41914). The deduced NH2‐terminal 10‐residue sequence is identical with that determined for purified LGP 107. The primary structure deduced for LGP 107 contains 20 potential N‐glycosylation sites and exhibits 82.5, 43 and 60% sequence similarities to mouse LAMP‐1, chicken LEP 100, and a 120‐kDa human lysosomal glycoprotein, respectively. Among these lysosomal glycoproteins, the amino acid sequence of the putative transmembrane segment is highly conserved. Northern blot hybridization analysis identified a single species of LGP 107 mRNA (2.1 kbp in length) in rat liver, kidney, brain, lung, spleen, heart and pancreas, although its level in pancreas was very low. |
