Summary: Enables diacylglycerol binding activity and triglyceride binding activity. Involved in several processes, including intracellular triglyceride homeostasis; lipid droplet formation; and positive regulation of sequestering of triglyceride. Acts upstream of or within sequestering of triglyceride. Located in endoplasmic reticulum membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and integumental system. Human ortholog(s) of this gene implicated in Siddiqi syndrome. Orthologous to human FITM2 (fat storage inducing transmembrane protein 2). [provided by Alliance of Genome Resources, Nov 2024]
Expression: Broad expression in heart adult (RPKM 53.0), adrenal adult (RPKM 50.4) and 19 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.
