|Product Overview :
||Recombinant Human DLL1 was produced inHEK 293cells. Signal peptide and extracellular domain of recombinant human DLL1 (Delta-like protein 1; Delta1) (aa 1-545) are fused at the C-terminus to a FLAG-tag.
||DLL1 is the human homolog of the Drosophila Notch ligand Delta. Sequence analysis predicted that the 723-aa DLL1 transmembrane protein, which is 88% identical to the mouse DLL1 protein, has a DSL domain followed by 8 tandem EGF-like repeats and a short cytoplasmic C-terminal region. A soluble fusion protein containing the DSL domain of DLL1 and its adjacent 50 N-terminal aa inhibited the differentiation of myeloid progenitors but promoted their expansion. DLL1 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. DLL1 undergoes proteolytic processing in its extracellular domain by ADAM10 and represents a substrate for several other members of the ADAM family. The soluble 38kDa Delta1 intracellular domain (DICD) that is generated by the presenilin-dependent γ-secretase cleavage is transported into the nucleus and likely plays a role in transcriptional events. Recently it has been shown that DLL1 is essential for postnatal arteriogenesis.
