Histocompatibility minor serpin domain (HMSD).

This basic part encodes Histocompatibility minor serpin domain which is predicted to be able to inhibit HtrA1 (BBa_K4165004).


Usage and Biology

This gene encodes a protein with a serpin-domain that may act as a serine protease inhibitor. This gene is predominantly expressed in myeloid cells. A splice variant encoding a minor histocompatibility antigen may be expressed as a result of a polymorphism in this gene. This type of inhibitor is predicted to have high affinity for trypsin-like proteases (serine proteases), and in our case it would act as an inhibitor for the trypsin-like catalytic domain of serine protease HtrA1[1]-[3].
