Background

Stomatin-like protein 2 (SLP-2 and also known as STOML2) is a lipid-anchored mitochondrial protein that is part of a large protein complex that regulates mitochondrial biogenesis and function. Proteomic studies identified SLP-2 as a widely expressed mitochondria-enriched protein (1). As a member of both the stomatin family and stomatin-prohibitin-flotillin-HfLC/K (SPFH) superfamily of proteins, SLP-2 forms large hetero-oligomeric complexes with other mitochondrial proteins, including prohibtin, mitofusin 2, and cardiolipin (2, 3). SLP-2 contains a highly conserved SPFH domain that mediates its ability to associate with the mitochondrial inner membrane and form specialized membrane microdomains. As an inner membrane organizer of other mitochondrial proteins, SLP-2 performs multiple mitochondrial functions, including regulation of mitochondrial biogenesis, energy/calcium homeostasis, translation, and mitochondrial-mediated cellular stress responses (3, 4, 5, 6, 7, 8). Enhanced SLP-2 expression is also associated with several human cancers, including gallbladder, rectal, and gastric cancer (9, 10, 11).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
