mcd99When coexpressed, mCD99 formed heterodimers with mCD99L2, as well as homodimers, and the heterodimers were localized more efficiently at the plasma membraneIn the case of mCD99, two adjacent O- glycosylation sites, Thr-45 and Thr-50 (NMKPT 45 PKAPT 50 PKKPS) are relevant for PILR ␣ recognition (13).
