Recombinant proteins for solute carrier family 22 member 18 antisense are available from various sources. In humans, this protein has a Uniprot ID of Q8N1D0. This protein is 253 amino acids in length and 27.1 kilodaltons in mass. This protein is encoded by the gene SLC22A18AS. Other names also exist, such as: beckwith-Wiedemann syndrome chromosomal region 1 candidate gene B protein, Beckwith-Wiedemann region 1B, Beckwith-Wiedemann syndrome chromosome region 1, candidate b, organic cation transporter-like 2 antisense, organic cation transporter-like protein 2 antisense protein, p27-Beckwith-Wiedemann region 1 B, solute carrier family 22 (organic cation transporter), member 1-like antisense, solute carrier family 22 (organic cation transporter), member 18 antisense, solute carrier family 22 member 1-like antisense protein, solute carrier family 22 member 18 antisense protein. As many as 2 isoforms have been named. This protein is conserved in other species, including: mouse, rat, chimpanzee, guinea pig.
