Extra Details:: NELL1 (neural EGF-like like protein 1) is an 89kD (predicted) member of the EGF-like domain containing family, Laminin G/NTSP1/Pentraxin gene superfamily of molecules. When secreted, NELL1 exists as a phosphoglycoprotein that can add as much as 50kD to the calculated MW. NELL1 has restricted expression, being limited to pre-B cells and osteoblasts, where it apparently promotes osteoblast maturation and bone formation. In tumors, it is found in neuroblastoma- derived cells. NELL1 is both secreted and retained intracellularly where it is phosphorylated by PKC. The human NELL1 precursor is 810aa in length. It contains a16aa signal sequence plus a 794aa mature region. The mature region possesses an N-terminal TSP domain (aa81-230), two VWFC domains (aa271-390), six consecutive EGF-like domains (aa391-631), and three additional C-terminal VWFC domains (aa632 807). Secreted NELL1 forms a 400-420kD noncovalent homotrimer. Over aa17-810, human NELL1 shares 93% aa identity with mouse and rat NELL1. Alternate splicing generates an additional isoform of human NELL1 hat lacks the fifth EGF-like domain. Applications: Suitable for use in Immunocytochemistry. Other applications not tested.
