Domaini

The PH 1 domain mediates the oligomerization in a calcium dependent manner By similarity.
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 By similarity.

Sequence similaritiesi

Belongs to the syntrophin family.
Contains 1 PDZ (DHR) domain.
Contains 2 PH domains.
