Protein attributes

Sequence length	780 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Calmodulin-binding protein which may function as scaffolding or signaling protein and may play a role in dendritic Ca2+ signaling.
Subunit structure	Interacts with protein phosphatase 2A (PP2A) Potential. Interacts with CTTNBP2; this interaction may regulate dendritic spine distribution of STRN. Activation of glutamate receptors weakens the interaction with CTTNBP2 By similarity.
Subcellular location	Cytoplasm By similarity. Membrane; Peripheral membrane protein By similarity. Cell projection › dendritic spine By similarity. Note: CTTNBP2-binding may regulate dendritic spine distribution By similarity.
Tissue specificity	Preferentially expressed in brain. Ref.1
Sequence similarities	Belongs to the WD repeat striatin family. Contains 6 WD repeats.
