Spire2 Gene Summary [Mouse]
Predicted to enable microtubule binding activity. Involved in several processes, including cytoskeleton organization; cytoskeleton-dependent cytokinesis; and intracellular transport. Located in cell cortex and cytoplasmic vesicle membrane. Colocalizes with cleavage furrow. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; heart ventricle; and limb. Orthologous to human SPIRE2 (spire type actin nucleation factor 2). [provided by Alliance of Genome Resources, Apr 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 Spire2 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
