Protein attributes

Sequence length	2390 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Probably plays an important role in neuronal membrane skeleton.
Subcellular location	Cytoplasm › cytoskeleton. Cytoplasm › cell cortex.
Tissue specificity	Highly expressed in brain, kidney, pancreas, and liver, and at lower levels in lung and placenta.
Involvement in disease	Spinocerebellar ataxia 5 (SCA5) [MIM:600224]: Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA5 is an autosomal dominant cerebellar ataxia (ADCA). It is a slowly progressive disorder with variable age at onset, ranging between 10 and 50 years. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.12
Sequence similarities	Belongs to the spectrin family. Contains 2 CH (calponin-homology) domains. Contains 1 PH domain. Contains 17 spectrin repeats.
Sequence caution	The sequence BAA32700.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
