Spire1 Gene Summary [Rat]
Predicted to enable microtubule binding activity. Predicted to be involved in several processes, including cytoskeleton organization; cytoskeleton-dependent cytokinesis; and positive regulation of mitochondrial fission. Predicted to act upstream of or within behavioral fear response and dendritic spine development. Predicted to be located in several cellular components, including Golgi apparatus; cleavage furrow; and mitochondrial outer membrane. Predicted to be active in cell cortex and cytoplasmic vesicle membrane. Orthologous to human SPIRE1 (spire type actin nucleation factor 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 rat Spire1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- FYVE domain like superfamily
- Protein Kinases, catalytic domain
- WH2
- protein binding
- Kinase non-catalytic C-lobe domain
