High impact information on Glycam1

  • This ligand has been named GlyCAM 1 (Gly-cosylation-dependent Cell Adhesion Molecule 1) because its adhesive interactions with the L selectin lectin domain require that the GlyCAM 1 polypeptide chain be appropriately modified with carbohydrates [1].
  • An additional interesting structure that may have relevance to the association of GlyCAM 1 with the lumenal surface of the endothelium was a potential amphipathic helix at the C terminus of the glycoprotein [1].
  • Finally, immunoprecipitation analysis of [35S]sulfate-labeled rat lymph nodes with either a mouse L selectin IgG chimera or a peptide antiserum directed against a relatively conserved portion of mouse GlyCAM 1 demonstrates a approximately 45-kDa sulfated ligand in rat lymph nodes that is analogous to that previously described for mouse lymph nodes [1].
  • The sequence of this clone reveals a serine/threonine-rich protein that is highly homologous with the mouse GlyCAM 1 [1].
  • HEV express several L-selectin ligands including CD34, GlyCAM-1, MAdCAM-1 and two sulfated glycoproteins (Sgp) of 200 kDa and 170 kDa which remain to be identified [2].

Biological context of Glycam1

  • These observations suggest that GlyCAM-1 expressed in the cochlear region is heterogenous in terms of its glycosylation [3].

Anatomical context of Glycam1


Analytical, diagnostic and therapeutic context of Glycam1

  • Moreover, RT-PCR of the cochlear tissue by the use of specific oligonucleotide primers for rat GlyCAM-1 generated a 378 bp product which was then verified by nucleotide sequencing to represent GlyCAM-1 [3].
