Lcn2 Gene Summary [Rat]
Enables enterobactin binding activity; identical protein binding activity; and protease binding activity. Involved in several processes, including cellular response to cytokine stimulus; memory; and regulation of hippocampal neuron apoptotic process. Located in extracellular space. Used to study intrahepatic cholangiocarcinoma and retinal degeneration. Biomarker of several diseases, including acute kidney failure; congenital diaphragmatic hernia; obesity; transient cerebral ischemia; and traumatic brain injury. Human ortholog(s) of this gene implicated in urinary tract infection. Orthologous to human LCN2 (lipocalin 2). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Lcn2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
