    made of a N and C cytoplasmic termini:
  • twelve transmembrane segments (12TM)
  • a large cytoplasmic tail
  • a sulfate transporter motif and a relatively hydrophobic region near the C terminus
  • the STAS domain (sulfate transporter and anti-sigma factor antagonist)
    interspecies homolog to C.elegans Y48G10A.3
  • sulfate permease family
  • SLC26 gene family of anion transporters
  • CATEGORY transport carrier
    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • sulfate transporter specificially expressed in spermatocytes and spermatids
  • critical component of the sperm annulus that is essential for proper sperm tail differentiation and motility
  • role in male fertility, either independently or through interaction and reciprocal regulation with co-localized proteins shown to affect fertility
  • sperm-specific member of the SLC26 family of anion exchangers, associating with the CFTR channel and strongly stimulating its activity
    a component
  • SLC26A8-CFTR complex impicated in the regulation of the chloride and bicarbonate fluxes required for sperm motility and capacitation
    small molecule
  • male germ cell Rho GTPase (MGCRG)
  • SLC26A8 and CFTR physically interact, and SLC26A8 expression strongly stimulates CFTR activity

    constitutional germinal mutation      
    heterozygous SLC26A8 missense mutations that abolish functional interaction with the CFTR channel and potentially contribute to subfertility in men by impairing sperm motility and capacitation
    Variant & Polymorphism
    Candidate gene
    Therapy target
  • in the mouse, deletion of Tat1 caused male sterility due to a lack of sperm motility, impaired sperm capacitation and structural defects of the flagella
  • Tat1 null males mice were sterile due to complete lack of sperm motility and reduced sperm fertilization potential (
