Protein attributes

Sequence length	105 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Insulin decreases blood glucose concentration. It increases cell permeability to monosaccharides, amino acids and fatty acids. It accelerates glycolysis, the pentose phosphate cycle, and glycogen synthesis in liver.
Subunit structure	Heterodimer of a B chain and an A chain linked by two disulfide bonds.
Subcellular location	Secreted.
Sequence similarities	Belongs to the insulin family.
