Gene Symbol

Lep

Protein Name

leptin

Synonyms

ob; obese;

Species

Mus musculus

Ensembl Protein

ENSMUSP00000067046

InnateDB Gene

IDBG-130781 (Lep)

Protein Structure

UniProt Annotation

Function

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.

Subcellular Localization

Secreted {ECO:0000305}.

Disease Associations

Note=Defects in Lep are the cause of profound obesity and type II diabetes.
