F3 Recombinant Monoclonal Antibody

Uniprot Id

P13726

Target Species

Human

Target Name

F3

Target Full Name

Tissue factor

Target Function

Initiates blood coagulation by forming a complex with circulating factor VII or VIIa. The [TF:VIIa] complex activates factors IX or X by specific limited proteolysis. TF plays a role in normal hemostasis by initiating the cell-surface assembly and propagation of the coagulation protease cascade.

Target Subcellular Location

[Isoform 1]: Membrane; Single-pass type I membrane protein.; [Isoform 2]: Secreted.

Target Protein Families

Tissue factor family

Target Tissue Specificity

Lung, placenta and pancreas.

Target Research Area

Cardiovascular

Target Synonyms

CD142; CD142 antigen; Coagulation factor III (thromboplastin tissue factor); Coagulation factor III; F3; FLJ17960; TF; TF_HUMAN; TFA; Thromboplastin; Tissue factor

Target Background

This gene encodes coagulation factor III which is a cell surface glycoprotein. This factor enables cells to initiate the blood coagulation cascades, and it functions as the high-affinity receptor for the coagulation factor VII. The resulting complex provides a catalytic event that is responsible for initiation of the coagulation protease cascades by specific limited proteolysis. Unlike the other cofactors of these protease cascades, which circulate as nonfunctional precursors, this factor is a potent initiator that is fully functional when expressed on cell surfaces, for example, on monocytes. There are 3 distinct domains of this factor: extracellular, transmembrane, and cytoplasmic. Platelets and monocytes have been shown to express this coagulation factor under procoagulatory and proinflammatory stimuli, and a major role in HIV-associated coagulopathy has been described. Platelet-dependent monocyte expression of coagulation factor III has been described to be associated with Coronavirus Disease 2019 (COVID-19) severity and mortality. This protein is the only one in the coagulation pathway for which a congenital deficiency has not been described. Alternate splicing results in multiple transcript variants.
