  • overexpressed in some cancer tissues relative to normal tissues, particularly kidney, liver and pancreatic cancers
  • a 734-base pair sequence in the fourth intron of the hCNT1 gene was spliced between exons 3 and 4, while exons 5, 13 and part of exon 6 were skipped
  • may serve as a potential cancer biomarker

    FAMILY
  • SLC28A family of transporter
  • concentrative nucleoside transporter (CNT) (TC 2.A.41) family
  • CATEGORY transport carrier
    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • renal reabsorption transporter of physiological nucleosides, pyrimidines, adenosin and drugs
  • concentrative nucleoside transporter, sodium dependent
  • mediating the cellular uptake of naturally occurring pyrimidine nucleosides and many structurally diverse anticancer and antiviral nucleoside analogs
  • SLC28A1, SLC28A2 are pyrimidine and purine nucleoside-selective, respectively
  • mediates the uptake of naturally occurring pyrimidine nucleosides, but also nucleoside analogs used in anticancer and antiviral therapy
  • fits the profile of a transceptor in a substrate translocation-independent manner and is likely to be relevant to tumor biology
  • is implicated in sensitizing solid tumors to nucleoside analogs
  • is a putative determinant for nucleoside analog chemoresistance in ovarian cancer
