Báo cáo khoa học: Tyrosine-dependent basolateral targeting of human connexin43–eYFP in Madin–Darby canine kidney cells can be disrupted by the oculodentodigital dysplasia mutation L90V

Polarized membrane sorting of connexin 43 (Cx43) has not been well-char-acterized. Based on the presence of a putative sorting signal, YKLV(286– 289), within its C-terminal cytoplasmic domain, we hypothesized that Cx43 is selectively expressed on the basolateral surface of Madin–Darby canine kidney (MDCK) cells in a tyrosine-dependent manner.
