FOCAL POINT While looking for enzymes that help make N-glycans, Pam Stanley (left) and Hung-Hsiang Huang stumbled on a protein, GnT1IP, that prevents cells from revamping their high mannose N-glycans. These stickier glycans could help fasten testicular germ cells to their supporting cells. At ER exit sites, GnT1IP (red) cozies up to GlcNAcT-I (green), the enzyme it inhibits.
