Note IDN3 (also known as Colon tumor susceptibility 2, DKFZp434L1319, FLJ13648, Mis 4, Scc-2, Delangin and Sister chromatid cohesion protein) is the mammalian homologue of Scc2 in S. cerevisiae and Mis4 in S. pombe. In yeast, this factor was originally identified genetically as being involved in sister chromatid cohesion; subsequent work has determined that it is not involved in cohesion directly but is required for the loading of cohesins onto chromatin during S phase. It shares 37% sequence identity with Nipped-B gene product of Drosophila, which facilitates enhancer-promoter communication of remote enhancers. The Drosophila protein is also homologous to a family of chromosomal adherins with broad roles in sister chromatid cohesion, chromosome condensation, and DNA repair.  IDN3 is a nuclear protein that is widely expressed and found at the highest levels in heart, skeletal muscle, fetal and adult liver, and fetal and adult kidney. The protein is also found, albeit at lower levels of expression in thymus, placenta, peripheral leukocyte and small intestine.  Multiple isoforms of the protein have been reported.

WB Image
Western blot using Affinity Purified anti-IDN3 antibody shows detection of bands at ~315 kDa and ~125 kDa corresponding to isoforms of IDN3 (arrow-heads) in mouse heart whole cell tissue extract. Approximately 35 µg of lysate was separated on a 4-8% gel by SDS-PAGE and transferred onto nitrocellulose. After blocking the membrane was probed with the primary antibody diluted to 1:1,500. Reaction occurred overnight at 4° followed by washes and reaction with a 1:20,000 dilution of IRDye™800 conjugated Rb-a-Goat IgG [H&L] MXHu (605-432-013) for 45 min at room temperature. IRDye™800 fluorescence image was captured using the Odyssey® Infrared Imaging System developed by LI-COR. IRDye is a trademark of LI-COR, Inc. Other detection systems will yield similar results.
