Protein kinase C-binding protein NELL2 is a secreted glycoprotein that in humans is encoded by the NELL2 gene.[5] It is a homolog of Nel, which is a gene present in the neural tissues of chickens.[6]

This gene encodes a cytoplasmic protein that contains six epidermal growth factor (EGF) -like repeats. The encoded heterotrimeric protein may be involved in cell growth regulation and differentiation. A similar protein in rodents is involved in craniosynostosis. An alternative splice variant has been described but its full length sequence has not been determined.[5]

Function

[edit]

NELL2 has been implicated to be involved in a variety of different functions including neuronal development, sperm maturation, cancer progression and bone development.[7][8][9][10]

NELL2 has been shown to have roles in neuronal polarization and axon growth.[11] NELL2 is a negative regulator of axon guidance in the SLIT-ROBO signalling pathway where it binds with the ROBO3/Rig-1 receptor.[12] It can also bind with ROBO2 under acidic conditions, where ROBO2 undergoes proteolytic cleavage.[8]

NELL2 expression has been linked to higher survival rates for female lung adenocarcinoma patients.[13]
