Analysis of the enzymes involved in PEN5 carbohydrate metabolism

ABSTRACT: Dr. Eric Vivier's lab would like to tackle the enzymes involved in PEN5 carbohydrate metabolism. We have generated these cell lines by repeated cell sorting and cell cloning of the parental HSB-2 T cell line and the parental JY B cell line. H+ are PEN5+ HSB-2 cells, H- are PEN5- HSB-2 cells; JY+ are PEN5+ HSB-2 cells, JY- are PEN5- HSB-2 cells. We have originally described a cell surface molecule called PEN5, as a sulfated lactosamine, that is selectively expressed on a mature subset of human NK cells (Vivier, J. Exp. Med. 1993). Later, we have shown that the PEN5 carbohydrate decorates PSGL-1, confering L-selectin binding properties (André et al. PNAS, 2000). We have recently performed a Glycan Array Screening via Core H (Glycomics 917). These studies indeed reveal a very nice binding of
