NELL1, Recombinant, Mouse, aa17-810 (IDH3GL, Neural EGF-like like Protein 1)

NELL1 (neural EGFпїЅlike like protein 1) is an ~140kD modular glycoprotein that plays an important role in bone physiology (1). NELL1 contains an NпїЅterminal Laminin GпїЅlike domain and three vWF-C domains interspersed with five tandem EGFпїЅlike domains (2). Mature mouse NELL1 shares 98% and 93% aa identity with rat and human NELL1, respectively. NELL1 can be retained in the cytosol where it interacts with ARP3 (apoptosis-related protein 3) and becomes phosphorylated by PKC (3, 4). NELL1 is secreted as an ~400kD noncovalent homotrimer of heavily glycosylated subunits (5). It is expressed in bone and in select B cell lines (6, 7). NELL1 promotes the osteogenic differentiation of adiposeпїЅderived stromal/stem cells and inhibits adipogenic differentiation (8). It does not promote osteoblastic differentiation from myoblasts, but it does enhance the activity of BMPпїЅ2 in that function (9). NELL1 interacts directly with osteoblasts via Integrin alpha3beta1 (10, 11) and promotes osteoblast differentiation and mineralization (3, 12, 13). It synergizes with BMPпїЅ2 to increase phosphate uptake through the transporters Pit1 and Pit2 in preпїЅosteoblasts (14). In vivo, NELL1 expression in the cranium is localized at sites of suture closure (6). Its overexpression induces multiple abnormalities in cranial development including premature suture closure (craniosyntosis) and overlapping sutures (12, 13). Experimental engrafting demonstrates the ability of NELL1 to promote new bone formation and the healing of calvarial defects (13, 15).\n\nSource:\nRecombinant protein corresponding to aa32-740 from mouse NELL1, CHO-derived.\n\nMolecular Weight:\n~125-165kD\n\nEndotoxin:\n<0.10EU/1ug (LAL method)\n\nStorage and Stability:\nLyophilized powder may be stored at -20 degrees C.
