PAMR1 (peptidase domain containing associated with muscle regeneration 1), also known as RAMP or FP938, is a 720 amino acid secreted protein that belongs to the peptidase S1 family. Consisting of one CUB domain, an EGF-like domain, a peptidase S1 domain and two sushi (CCP/SCR) domains, PAMR1 may participate in regeneration of skeletal muscle. PAMR1 is strongly down-regulated in muscle cell lines derived from Duchenne muscular dystrophy (DMD) patients compared to a normal muscle cell line. DMD is the second most common genetically inherited disease in humans and is characterized by progressive limb-girdle distribution of muscle weakness. PAMR1 exists as two alternatively spliced isoforms and is encoded by a gene located on human chromosome 11, which contains 135 million base pairs and 1,400 genes, making up around 4% of human genomic DNA. |
