Detection of Human PAMR1 by Western Blot. Western blot shows lysates of U2OS human osteosarcoma cell line. PVDF Membrane was probed with 1 µg/mL of Human PAMR1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6517) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for PAMR1 at approximately 80 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

PAMR1 (Peptidase domain associated with muscle regeneration 1; also RAMP/ regeneration-associated muscle protease homolog) is a secreted, 80 kDa (predicted) member of the peptidase S1 family of enzymes. It is expressed by skeletal muscle, and appears to mediate skeletal muscle regeneration. Due to the lack of a catalytic serine at amino acid (aa) 672, PAMR1 demonstrates no enzyme activity. Mature PAMR1 is 716 aa in length (aa 22-737). It contains a Cys-rich segment (aa 42-94), one CUB domain (aa 128-234), an EGF-like region (aa 235-272), two SUSHI domains (aa 278-444) and a nonfunctional peptidase S1 domain (aa 445-737). There is one 17 aa deletion after Glu276. Over aa 21-737, human PAMR1 shares 88% aa identity with mouse PAMR1.
