Atxn2 Gene Summary [Rat]
Predicted to enable epidermal growth factor receptor binding activity and mRNA binding activity. Predicted to be involved in P-body assembly; negative regulation of receptor internalization; and stress granule assembly. Predicted to act upstream of or within several processes, including homeostasis of number of cells; neuromuscular process; and neuron differentiation. Predicted to be located in cytosol; perinuclear region of cytoplasm; and trans-Golgi network. Predicted to be part of ribonucleoprotein complex. Predicted to be active in cytoplasmic stress granule. Human ortholog(s) of this gene implicated in late onset Parkinson's disease and spinocerebellar ataxia type 2. Orthologous to human ATXN2 (ataxin 2).

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 Atxn2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
