Alpha-2-macroglobulin-like 1 abbreviated as α2ML1 is a protein that in humans is encoded by the A2ML1 gene.^[3] α2ML1 is a large, 180 kDa protein found in the epidermis. It is able to the inhibit the chymotryptic activity of KLK7.^[4]

Function[edit]

This gene encodes a member of the alpha-macroglobulin superfamily. The encoded protein acts as an inhibitor for several proteases, and has been reported as the p170 antigen recognized by autoantibodies in the autoimmune disease paraneoplastic pemphigus (PNP).^[5] Alternative splicing results in multiple transcript variants.^[3]

Clinical significance[edit]

Mutations in A2ML1 are associated to Noonan-like syndrome.^[6]
