Phactr1 Gene Summary [Mouse]
Enables actin binding activity. Involved in nervous system development; regulation of neuron migration; and stress fiber assembly. Located in cytosol and nucleus. Is expressed in several structures, including central nervous system and neural retina. Human ortholog(s) of this gene implicated in artery disease (multiple) and brain disease (multiple). Orthologous to human PHACTR1 (phosphatase and actin regulator 1). [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 mouse Phactr1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- RPEL repeat
- protein phosphatase 1 binding
- actin binding
