A genetic clog in the vitamin A transport machinery

Cell. 2015 Apr 23;161(3):435-437. doi: 10.1016/j.cell.2015.04.020.

Abstract

Chou et al. discover a new mode of maternal inheritance by analyzing human mutations in plasma retinol binding protein (RBP). Mechanistically, these mutations simultaneously lower RBP's affinity for vitamin A and greatly increase its affinity for its cell-surface receptor, thus dominantly blocking the transmembrane transport of vitamin A.
