HspB2 was discovered as a chaperone of muscular dystrophy protein kinase (DMPK) and originally named, DMPK binding protein (MKBP) and presently called HspB2. Functionally, MKBP binds to DMPK and stabilizes its kinase activity, thereby accelerating the progression of muscular dystrophy. Although other binding partners of HspB2 have been found, the...
