Summary The myosin light chain composition of sheep interatrial and interventricular septa were analysed by one- and two-dimensional polyacrylamide gel. The interventricular septum has myosin light chain composition indistinguishable from that of ventricular myosin. Myosin from the interatrial septum contains three light chains, two of which co-migrated with the two atrial light chains (ALC1 and ALC2), while the third co-migrated with ventricular light chain 2 (VLC2). ALC1 are more abundant than ALC2 or VLC2 suggesting a mixed myosin population. Myosin with ALC1 and VLC2 light chain composition may be present, and its possible relationship with cardiac “conducting” cells is discussed.
