Molecular determinants of species specificity in the coronavirus receptor aminopeptidase N (CD13): influence of N-linked glycosylation.
Aminopeptidase N (APN), a 150-kDa metalloprotease also called CD13, serves as a receptor for serologically related coronaviruses of humans (human coronavirus 229E [HCoV-229E]), pigs, and cats. These virus-receptor interactions can be highly species specific; for example, the human coronavirus can use human APN (hAPN) but not porcine APN (pAPN) as its cellular receptor, and porcine coronaviruses...
متن کاملBiological significance of aminopeptidase N/CD13 in thyroid carcinomas.
Aminopeptidase N (APN)/CD13 is a transmembrane ectopeptidase expressed on a wide variety of cells. However, the precise function of APN/CD13 in tumor cells and the relationship of APN/CD13 to thyroid cancer remain unclear. In our study, we quantified the expression of APN/CD13 and additionally dipeptidyl peptidase IV (DPIV)/CD26 in thyroid carcinoma cell lines and in tissues of patients with th...
متن کاملCD13 (human aminopeptidase N) mediates human cytomegalovirus infection.
Human cytomegalovirus (HCMV) infects cells by a series of processes including attachment, penetration via fusion of the envelope with the plasma membrane, and transport of the viral DNA to the nucleus. The details of the early events of HCMV infection are poorly understood. We have recently reported that CD13, human aminopeptidase N, a metalloprotease, is present on blood cells susceptible in v...
متن کاملNovel, aberrantly truncated isoform of serum CD13 in a family with high serum aminopeptidase N (CD13) activity.
BACKGROUND We previously reported a family in which the propositus and both her father and paternal grandmother had high serum aminopeptidase N (CD13; EC 3.4.11.2) activity (autosomal dominant). The molecular mass of the serum CD13 polypeptide of the propositus was larger than that of normal CD13, suggesting either a mutation in the CD13 gene or an abnormality in posttranslational modification ...
متن کاملMetalloprotease activity of CD13/aminopeptidase N on the surface of human myeloid cells.
We previously found that the myeloid cell surface glycoprotein CD13 (gp150) is identical to aminopeptidase N (EC 3.4.11.2), a widely distributed membrane-bound, zinc-dependent metalloprotease with an extracellular enzymatic domain that cleaves N-terminal amino acid residues from oligopeptides (J Clin Invest 83:1299, 1989). As a first step toward defining the function of this molecule on myeloid...
