Primary structure analysis of an integral membrane glycoprotein of the nuclear pore

PMCID: PMC2115607  PMID: 2738089

Abstract

The complete primary structure of an integral membrane glycoprotein of the nuclear pore was deduced from the cDNA sequence. The cDNA encodes a polypeptide of 204,205 D containing a 25-residue-long signal sequence, two hydrophobic segments that could function as transmembrane segments, and 13 potential N-linked oligosaccharide addition sites. Endoglycosidase H reduces the molecular mass by approximately 9 kD suggesting that not all of these 13 sites are used. We discuss possible models for the topology of this protein in the pore membrane as well as a possible role in the formation of pores and pore complexes.
