Adenosine 3'-phospho 5'-phosphosulfate transporter 2 (SLC35B3)

Mediates the transport of adenosine 3'-phospho 5'- phosphosulfate (PAPS), from cytosol into Golgi. PAPS is a worldwide sulfuryl donor for sulfation events which happen in the Golgi.

Compensates for the insufficient expression of SLC35B2/PAPST1 during the synthesis of sulfated glycoconjugates in the colon. .
