Also known as: SMP2
Summary: Enables phosphatidate phosphatase activity and transcription cis-regulatory region binding activity. Involved in several processes, including lipid droplet organization; triglyceride biosynthetic process; and vacuole fusion, non-autophagic. Located in cytosol; lipid droplet; and vacuole. Is active in nuclear membrane. Used to study lipid metabolism disorder and myoglobinuria. Human ortholog(s) of this gene implicated in chronic recurrent multifocal osteomyelitis. Orthologous to human LPIN1 (lipin 1); LPIN2 (lipin 2); and LPIN3 (lipin 3). [provided by Alliance of Genome Resources, Nov 2024]
