General annotation (Comments)

Function

Major transport protein for glucocorticoids and progestins in the blood of almost all vertebrate species. Ref.5

Subcellular location

Secreted.

Tissue specificity

Expressed by the liver; secreted in plasma. Ref.1

Domain

Proteolytic cleavage leads to an important conformation change. This reduces the affinity for steroids By similarity.

Sequence similarities

Belongs to the serpin family.
