Other proteins shown to interact with H11/HspB8 include Src-associated protein in mitosis 68 kDa (Sam68), which is involved in RNA transportation and processing [45], Ddx20, that has helicase activity [46], and β-crystallin mutants associated with the development of desmin-related cardiomyopathy or myofibrillar myopathy [47]. Here, KHDRBS1 is linked to myofibrillar myopathy.
