Lipocalin 2 has been implicated in a variety of processes including cell differentiation, tumorigenesis, and apoptosis (1-3).
It binds a bacterial catecholate sidropore bound to ferric ion such as enterobactin with a subnanomolar dissociation constant (KD = 0.41nM) (4).
The bound ferric enterobactin complex breaks down slowly in a month into dihydroxybenzoyl serine and dihydroxybenzoic acid (DHBA).
It also binds to a ferric DHBA complex with much less KD values (7.9nM) (4).
Secretion of Lipocalin 2 in immune cells increases by stimulation of Toll-like receptor as a acute phase response to infection.
As a result, it acts as a potent bacteriostatic reagents by sequestering iron (5).
Moreover, Lipocalin-2 can alter the invasive and metastatic behavior of Ras-transformed breast cancer cells in vitro and in vivo by reversing epithelial to mesenchymal transition inducing activity of Ras, through restoration of E-cadherin expression, via effects on the Ras-MAPK signaling pathway (6).
In the kidney, Lipocalin 2-mediated iron trafficking may be involved in protection from renal injury, and it has been implicated as a marker for early kidney failure (7, 8).
