Polymorphism of delta3,5-delta2,4-dienoyl-coenzyme A isomerase (the ECH1 gene product protein) in human striated muscle tissue.

Two polymorphic variants of the ECH1 gene product protein (delta3,5-delta2,4-dienoyl-coenzyme A isomerase) have been revealed by proteomics methods in samples of human striated muscle tissue. These variants are identical in molecular weight (29.7 kD) but different in pI values (6.
