ASPRV1 Recombinant Protein

Source : Escherichia Coli. ASPRV1 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 159 amino acids (191-326) and having a molecular mass of 17.2kDa.ASPRV1 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Aspartic Peptidase, Retroviral-Like 1 (ASPRV1) is a protein which contains one peptidase A2 domain. ASPRV1 undergoes autocleavage which is essential for activation of the protein. ASPRV1 is expressed mostly in the granular layer of the epidermis and inner root sheath of hair follicles and localized to membrane region. In the psoriatic skin, ASPRV1 is expressed throughout the stratum corneum. In the ulcerated skin, ASPRV1 is expressed in the stratum granulosum of intact epidermis; however it is virtually nonexistent from ulcerated regions. In addition, ASPRV1 is expressed in differentiated areas of squamous cell carcinomas but not in the undifferentiated tumors.
