  • Function
    Acts as a ligand for Notch receptors. Blocks the differentiation of progenitor cells into the B-cell lineage while promoting the emergence of a population of cells with the characteristics of a T-cell/NK-cell precursor.
  • Tissue specificity
    Expressed in heart and pancreas, with lower expression in brain and muscle and almost no expression in placenta, lung, liver and kidney.
  • Sequence similarities
    Contains 1 DSL domain.
    Contains 8 EGF-like domains.
  • Post-translational
    Ubiquitinated by MIB (MIB1 or MIB2), leading to its endocytosis and subsequent degradation.
  • Cellular localization
  • Information by UniProt

Recombinant Mouse DLL1 protein images

  • Adipogenesis inhibition. Macroscopic pictures.
  • Adipogenesis inhibition of 3T3L1 cells.
    3T3L1 cells were maintained in DMEM, supplemented with 10% fetal bovine serum, penicilin-streptomycin. Adipogenesis was initiated by adding 1µM Dexamethasone, 0.5mM IBMX, 10µg/m lnsulin (day 0) until day 2. The medium was replaced every 2 days with new medium containing insulin in the presence or absence of 5µg/ml mDLL1-Fc (ab108549) and hCD137-Fc (Fc control). Staining with Oil Red O was typically performed on day 7. Cells were washed twice with PBS, fixed with 3.7% formalin, and stained with 0.5% filtered Oil Red O in propylene glycol.
  • Induction of Hes-1 with the treatment of recombinant mouse DLL1-Fc (ab108549).
    A mouse preadpipocyte cell line, 3T3L1, was stimulated with 5mg/ml of mouse DLL1-Fc (ab108549) as in indicated time points and each cell lysate was prepared and subjected to western blot by using anti-mouse Hes1 or GAPDH.
