General annotation (Comments)

Function

Factor XI triggers the middle phase of the intrinsic pathway of blood coagulation by activating factor IX By similarity.

Catalytic activity

Selective cleavage of Arg-|-Ala and Arg-|-Val bonds in factor IX to form factor IXa.

Subunit structure

Homodimer; disulfide-linked. After activation the heavy and light chains are also linked by a disulfide bond By similarity.

Subcellular location

Secreted By similarity.

Post-translational modification

Activated by factor XIIa (or XII), which cleaves each polypeptide after Arg-387 into the light chain, which contains the active site, and the heavy chain, which associates with high molecular weight (HMW) kininogen By similarity.

Involvement in disease

Defects in F11 are the cause of factor XI deficiency in Japanese black cattle. It is an hereditary mild bleeding disorder with an autosomal recessive mode of inheritance.

Sequence similarities

Belongs to the peptidase S1 family. Plasma kallikrein subfamily.

Contains 4 apple domains.

Contains 1 peptidase S1 domain.
