Solute carrier family 22 (organic cation transporter), member 21 is a protein that in the house mouse is encoded by the Slc22a21 gene. The gene is also known as Octn3 and Slc22a9. Slc22a21 belongs to a protein family of solute carriers.
Model organisms
Model organisms have been used in the study of Slc22a21 function. A conditional knockout mouse line, called Slc22a21tm1a(KOMP)Wtsi was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute.
Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Twenty five tests were carried out on mutant mice but no significant abnormalities were observed.
