Summary: Predicted to enable actin binding activity. Involved in several processes, including cytoskeleton organization; cytoskeleton-dependent cytokinesis; and positive regulation of mitochondrial fission. 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. Is integral component of mitochondrial outer membrane. Colocalizes with cleavage furrow. Is expressed in central nervous system; dorsal root ganglion; genitourinary system; liver; and spleen. Orthologous to human SPIRE1 (spire type actin nucleation factor 1). [provided by Alliance of Genome Resources, Apr 2022]
Expression: Broad expression in cerebellum adult (RPKM 16.5), frontal lobe adult (RPKM 16.3) and 22 other tissues See more

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.
