  • Function

    Seems to play a role in testicular function. May be a trophic hormone with a role in testicular descent in fetal life. Is a ligand for LGR8 receptor.
  • Tissue specificity

    Expressed in prenatal and postnatal Leydig cells. Found as well in the corpus luteum, trophoblast, fetal membranes and breast.
  • Involvement in disease

    Defects in INSL3 seems to be a cause of cryptorchidism (CRYPTO) [MIM:219050]; also known as impaired testicular descent. It is one of the most frequent congenital abnormalities in humans, involving 2-5% of male births. Cryptorchidism is associated with increased risk of infertility and testicular cancer. The frequency of INSL3 gene mutations as a cause of cryptorchidism is low.
  • Sequence similarities

    Belongs to the insulin family.

    INSL3 is expressed in prenatal and postnatal Leydig cells. Human fetal heart, kidney, spleen, NCCIT, A431 & Jurkat cells represent negative controls in this experiment.

    Blocking/Dilution buffer: 5% NFDM/TBST.

  • INSL3 was immunoprecipitated from 1mg of Human testis whole cell lysate with ab199536 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab199536 at 1/1000 dilution. Anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG, was used as secondary antibody at 1/1500 dilution.

    Lane 1: Human testis whole cell lysate 10 µg (Input). Lane 2: ab199536 IP in Human testis whole cell lysate. Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab199536 in Human testis whole cell lysate.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.
