Areg Gene Summary [Rat]
Enables epidermal growth factor receptor binding activity and growth factor activity. Involved in several processes, including negative regulation of osteoblast differentiation; neurogenesis; and response to hydrogen peroxide. Located in extracellular space. Used to study high grade glioma. Human ortholog(s) of this gene implicated in breast cancer. Orthologous to human AREG (amphiregulin). [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 Areg often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.

- cytoplasmic domain
- epidermal growth factor receptor binding
- ectodomain
- nuclear localization sequence
