Summary: Predicted to enable phospholipid binding activity. Involved in several processes, including fat cell differentiation; positive regulation of cold-induced thermogenesis; and regulation of lipid metabolic process. Acts upstream of or within several processes, including adipose tissue development; cytosolic lipolysis; and lipid droplet formation. Located in endoplasmic reticulum. Is expressed in brown fat; early conceptus; and secondary oocyte. Used to study congenital generalized lipodystrophy type 2 and male infertility. Human ortholog(s) of this gene implicated in autosomal dominant distal hereditary motor neuronopathy 13; congenital generalized lipodystrophy type 2; hereditary spastic paraplegia; hereditary spastic paraplegia 17; and lipodystrophy. Orthologous to human BSCL2 (BSCL2 lipid droplet biogenesis associated, seipin). [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.
