Summaries for SNTB1 Gene

Entrez Gene Summary for SNTB1 Gene

  • Dystrophin is a large, rod-like cytoskeletal protein found at the inner surface of muscle fibers. Dystrophin is missing in Duchenne Muscular Dystrophy patients and is present in reduced amounts in Becker Muscular Dystrophy patients. The protein encoded by this gene is a peripheral membrane protein found associated with dystrophin and dystrophin-related proteins. This gene is a member of the syntrophin gene family, which contains at least two other structurally-related genes. [provided by RefSeq, Jul 2008]

  • The PH 1 domain mediates the oligomerization in a calcium dependent manner.
  • Belongs to the syntrophin family.
  • The PH 1 domain mediates the oligomerization in a calcium dependent manner.
  • The PDZ domain binds to the last three or four amino acids of ion channels and receptor proteins. The association with dystrophin or related proteins probably leaves the PDZ domain available to recruit proteins to the membrane (By similarity).
  • The SU domain binds calmodulin in a calcium-dependent manner.
  • Contains 1 PDZ (DHR) domain.
  • Contains 2 PH domains.
  • Contains 1 SU (syntrophin unique) domain.
  • Belongs to the syntrophin family.
