Function

Serpin or serine protease inhibitor (Ser) are protease inhibitors.

Ser C1 is Antithrombin.
Ser A5 is protein C inhibitor.
Ser A6 is Corticosteroid-binding globulin.
Ser A8 is angiotensinogen.
Ser A7 is a thyroxine-binding globulin.
Ser B1 is leukocyte elastase inhibitor^[1].
Ser B3 is squamos cell carcinoma antigen 1^[2].
Ser B5 is Maspin^[3].
Ser crmA is cysteine and serine proteinase inhibitor^[4].
Ser I1 is neuroserpin.
Ser A10 is protein Z-related protease inhibitor.
Ser A1 is Alpha-1-antitrypsin.
Ser A3 is α 1-antichymotrypsin.
Ser E1 is Plasminogen activator inhibitor.

Disease

Mutation in Ser A7 causes partial thyroxine-binding globulin deficiency^[5]. Ser B3 may contribute to tumor cell resistance to anti-neoplastic drugs^[6]. Ser A3 promotes growth of endometrial cancer cells ^[7].

Structural highlights

Ser A7 - a thyrosine-binding globulin - binding site contains thyroxin derivative^[8].
