General description

FUNCTION: SwissProt: P41159 # May function as part of a signaling pathway that acts to regulate the size of the body fat depot. An increase in the level of LEP may act directly or indirectly on the CNS to inhibit food intake and/or regulate energy expenditure as part of a homeostatic mechanism to maintain constancy of the adipose mass.
SIZE: 167 amino acids; 18641 Da
SUBUNIT: Interacts with SIGLEC6.
SUBCELLULAR LOCATION: Secreted.
DISEASE:SwissProt: P41159 # Defects in LEP may be a cause of autosomal recessive obesity [MIM:601665].
SIMILARITY: SwissProt: P41159 ## Belongs to the leptin family.

Application

Overnight, equilibrium incubation at 4°C. Sample volume 100 μL serum, plasma, or tissue culture media.

Analysis Note
