Protein attributes

Sequence length	306 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Inhibits factor X (X(a)) directly and, in a Xa-dependent way, inhibits VIIa/tissue factor activity, presumably by forming a quaternary Xa/LACI/VIIa/TF complex. It possesses an antithrombotic action and also the ability to associate with lipoproteins in plasma By similarity.
Subcellular location	Secreted.
Tissue specificity	Isoform alpha is expressed in heart and spleen; isoform beta in heart and lung.
Domain	This inhibitor contains three inhibitory domains. The first domain interacts with VIIa and TF, the second one with Xa By similarity.
Sequence similarities	Contains 3 BPTI/Kunitz inhibitor domains.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]

Isoform Alpha (identifier: O54819-1)

Also known as: TFPIalpha;

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Isoform Beta (identifier: O54819-2)

Also known as: TFPIbeta;

The sequence of this isoform differs from the canonical sequence as follows:
     218-253: DYRGRPWCLQPADSGLCKASERRFYYNSATGKCHRF → VTKEETNGGWKNADYTYQGFLSSVYIHVLYFVFRIG
     254-306: Missing.
