Summary
Predicted to enable lipid binding activity and ubiquitin protein ligase binding activity. Predicted to be involved in several processes, including abscission; lipophagy; and negative regulation of BMP signaling pathway. Predicted to act upstream of or within several processes, including adipose tissue development; lipid droplet organization; and negative regulation of collateral sprouting in absence of injury. Predicted to be located in several cellular components, including lipid droplet; midbody; and mitochondrial outer membrane. Predicted to be active in plasma membrane. Human ortholog(s) of this gene implicated in Troyer syndrome. Orthologous to human SPART (spartin). [provided by Alliance of Genome Resources, Oct 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.
