TRAM Antibody

By crosslinking and reconstitution of canine proteoliposomes, followed by microsequencing and PCR screening of canine kidney and HeLa cell cDNA libraries, Gorlich et al.(1992) isolated cDNAs encoding TRAM (translocating chain-associating membrane protein). The International Radiation Hybrid Mapping Consortium mapped the gene to chromosome 8. Sequence analysis predicted that human TRAM is a 374-amino acid, 8-pass transmembrane protein that shares 95% amino acid identity with the canine protein. Functional analysis indicated that the protein influences glycosylation and is stimulatory or required for the translocation of secretory proteins.
