Target

  • Function

    The insulin-like growth factors possess growth-promoting activity. In vitro, they are potent mitogens for cultured cells. IGF-II is influenced by placental lactogen and may play a role in fetal development.
    Preptin undergoes glucose-mediated co-secretion with insulin, and acts as physiological amplifier of glucose-mediated insulin secretion. Exhibits osteogenic properties by increasing osteoblast mitogenic activity through phosphoactivation of MAPK1 and MAPK3.
  • Involvement in disease

    Epigenetic changes of DNA hypomethylation in IGF2 are a cause of Silver-Russell syndrome (SIRS) [MIM:180860]. SIRS is a clinically heterogeneous condition characterized by severe intrauterine growth retardation, poor postnatal growth, craniofacial features such as a triangular shaped face and a broad forehead, body asymmetry, and a variety of minor malformations.
  • Sequence similarities

    Belongs to the insulin family.
  • Post-translational
    modifications

    O-glycosylated with a core 1 or possibly core 8 glycan.
  • Cellular localization

    Secreted.

    Asked on May 09 2014

    Answer


    We haven't tested the cross-reactivity of ab177467 with IGF-1.
    However, based on the the immunogen sequence analysis the homology of the immunogen peptide is only 50% and no continuous sequences more than 3 aa could be found.
    It seems that there may be very little cross reactivity with IGF-1 (UniProt entry number P05019).

    Question

    Obtaining a strong 50 kDa band and a faint 15 kDa band with ab177467. There seems to be a very faint band right below 50 kDa in the datasheet WB image, do you have any idea what this band is?

    Asked on Mar 25 2014

    Answer

    The laboratory completed the blocking study for ab177467 (IGF2), and found that the blocking peptide did successfully block the 50 kDa band, indicating that this band is associated with the immunogen.

    We found the 2 attached papers, which cite that a 50 kDa complex does exist for both IGF1 and IGF2 in serum, so these complexes may be present in your mouse skin as well.

    From IGF1 paper:

    “In serum, the majority (70–80%) of the IGFs exist in a 150-kDa complex comprised of one IGF molecule, IGFBP-3, and the acid labile subunit (ALS). A smaller proportion (∼20%) of the IGFs are associated with other serum IGFBPs within a 50-kDa complex, and less than 5% of the IGFs are found in the free form of 7.5 kDa.”

    From IGF2 paper:

    ˜50kDa complex formed by IGF-II and IGFBP in the circulation.
