    Summary
    Enables glycerol kinase activity. Involved in triglyceride biosynthetic process. Acts upstream of or within glucose homeostasis; glycerol metabolic process; and regulation of fatty acid metabolic process. Located in mitochondrion. Is active in cytosol. Is expressed in several structures, including brain; brown fat; genitourinary system; liver; and spleen. Used to study glycerol kinase deficiency. Human ortholog(s) of this gene implicated in glycerol kinase deficiency. Orthologous to human GK (glycerol kinase). [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.
