    Summary
    Acts upstream of or within several processes, including chylomicron remnant clearance; positive regulation of lipoprotein lipase activity; and regulation of lipid metabolic process. Located in endoplasmic reticulum membrane. Is expressed in several structures, including 1st branchial arch mandibular component; adipose tissue; central nervous system; liver; and vertebral cartilage condensation. Human ortholog(s) of this gene implicated in familial lipase maturation factor 1 deficiency. Orthologous to human LMF1 (lipase maturation factor 1).

    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.
