Figure 2.

Diagrammatic representation of the small, alternatively spliced ankyrin of skeletal muscle relative to the large, erythroid ankyrin. The three major domains of a typical erythroid ankyrin are indicated. The region of the small ankyrin shared with the larger protein is shown by a shaded bar. The novel region containing a stretch of hydrophobic amino acids at the NH₂ terminus is shown as an open bar. The locations of the epitopes of the two antibodies, anti-p65 and anti-p6, are underlined. The long isoform depicted in this figure is Cb14/11 from Birkenmeier et al., 1993.
