该基因编码一个转运肉碱的两性离子转运蛋白家族成员。编码的蛋白质也被证明可以运输抗癌药物如博莱霉素（pmid:20037140），成功的治疗与肿瘤细胞中这种转运蛋白的活性水平有关。[由RefSeq提供，2011年12月]
This gene encodes a member of the organic zwitterion transporter protein family which transports carnitine. The encoded protein has also been shown to transport anticancer drugs like bleomycin (PMID: 20037140) successful treatment has been correlated with the level of activity of this transporter in tumor cells.
