Sequence Features

 101S -> R (in CMH17; modifies the secondary structure of the protein which is more flexible but does not undergo structural transition upon binding to membrane lipids; increases the affinity for phosphatidylserine; affects intracellular calcium handling and homeostasis). VAR_065471
 141Y -> H (in CMH17; results in vacuolization of intracellular structures and cardiomyocyte hypertrophy; affects intracellular calcium handling and homeostasis; dbSNP:rs387906897). VAR_065472 dbSNP
 165S -> F (in CMH17; results in vacuolization of intracellular structures and cardiomyocyte hypertrophy; affects intracellular calcium handling and homeostasis. Greatly reduced phosphorylation. Increased myotube diameter. Reduced RYR1 activity and EC gain. Disruption of interaction with TRPC3; dbSNP:rs387906898). VAR_065473 dbSNP
 396A -> T (in dbSNP:rs3810510). VAR_053447 dbSNP
 436R -> C. VAR_065474
 505G -> S (in patients with cardiomyopathy; does not affect protein conformation as shown by circular dichroism; a patient with cardiomyopathy also carries V-26 and C-513 in MYH7; dbSNP:rs140740776). VAR_065475 dbSNP
 675-695Helical; Anchor for type IV membrane protein.
