SLC35B4 encodes the human gene, Solute carrier family 35 (UDP-xylose/UDP-N-acetylglucosamine transporter), member B4. It may also be known as: UDP-xylose and UDP-N-acetylglucosamine transporter; YEA4 homolog; Solute carrier family 35 member B4; YEA; YEA4. The encoded protein has an amino acid length of 331 and a mass of 37.4 kDa. Other isoforms may exist. SLC35B4 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.
