SLC35B2 encodes the human gene, Solute carrier family 35 (adenosine 3'-phospho 5'-phosphosulfate transporter), member B2. It may also be known as: Adenosine 3'-phospho 5'-phosphosulfate transporter 1; Putative MAPK-activating protein PM15; Putative NF-kappa-B-activating protein 48; Solute carrier family 35 member B2; PAPS transporter 1; PAPST1; SLL; UGTrel4. The encoded protein has an amino acid length of 432 and a mass of 47.5 kDa. Other isoforms may exist. SLC35B2 is a member of the Nucleotide-sugar transporter family, SLC35B subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
