Description

The recombinant human ALPP protein is encoded by a recombinant DNA that was cloned into the expression vector and then transformed into the Baculovirus that supports the expression of the gene. The recombinant DNA was constructed by fusing the N-terminal 10xHis tag gene to the gene fragment coding for the 117-447aa of the human ALPP protein. After purification, the product is the recombinant human ALPP protein. This recombinant ALPP protein was subjected to the SDS-PAGE determination. Its purity reaches over 85% evaluated by Bandscan software analysis combined with SAS-PAGE. This ALPP protein ran to the molecular weight of about 40 kDa under SDS-PAGE condition.

ALPP (or PLAP) protein is an allosteric enzyme encoded by the ALPP gene. ALPP belongs to a multigene family composed of four alkaline phosphatase isoenzymes. ALPP is a membrane-bound glycosylated dimeric enzyme, which is mainly presented on the placental and endometrial tissue. It usually functions as a homodimer. At present, the ALPP protein has been discovered involvement in coronavirus biology, which is relevant for disease process. As identified tumor target, ALPP participates in the progress of tumors like seminoma and ovarian cancer.
