The Pho1 phosphate permease family (TC# 2.A.94) is a family of phosphate transporters belonging to the ion transporter (IT) superfamily. Representative members of the Pho1 family include the putative phosphate transporter PHO1 of Arabidopsis thaliana (TC# 2.A.94.1.1), and the xenotropic and polytropic murine-leukemia virus receptor Xpr1 of Culex pipiens (TC# 2.A.94.1.2).
