Also known as: Spir-1; 6030430B19Rik
Summary: Predicted to enable microtubule binding activity. Involved in several processes, including cytoskeleton organization; cytoskeleton-dependent cytokinesis; and intracellular transport. Acts upstream of or within Golgi vesicle transport; behavioral fear response; and dendritic spine development. Located in Golgi apparatus; cell cortex; and cytoplasmic vesicle membrane. Colocalizes with cleavage furrow. Is expressed in several structures, including central nervous system; genitourinary system; intestine; liver; and spleen. Orthologous to human SPIRE1 (spire type actin nucleation factor 1). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
