Summary
Enables triacylglycerol lipase activity. Involved in lipid droplet organization and triglyceride catabolic process. Acts upstream of or within positive regulation of mitochondrial fission. Located in membrane. Used to study hereditary spastic paraplegia 54. Human ortholog(s) of this gene implicated in hereditary spastic paraplegia 54. Orthologous to human DDHD2 (DDHD domain containing 2). [provided by Alliance of Genome Resources, Nov 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.
