Subcellular distribution of mammalian obscurin proteins in skeletal and cardiac muscle. Known locations for obscurins are highlighted by a distinct color: purple subsarcolemma, light green nulei, blue intercalated disc, yellow neuromuscular junction, orange A/I junction, dark green Z-disc, red M-band. A summary of the functions of obscurin at these locations is also noted. PP2A Protein phosphatase 2, RhoA Ras homolog gene family, member A, SR sarcoplasmic reticulum
