SLC63 Sphingosine-phosphate transporters C

Unless otherwise stated all data on this page refer to the human proteins. Gene information is provided for human (Hs), mouse (Mm) and rat (Rn).

Overview

Show »« Hide

The SLC63 family of transporters has roles inside the cell (SLC63A1/SPNS1) or on the cell surface (SLC63A2/SPNS2) in sphingolipid transport.
