[5][6] The product of this gene belongs to the phosphatase 2regulatory subunit B family.

The B regulatory subunit might modulate substrate selectivity and catalytic activity.

This gene encodes a beta isoform of the regulatory subunit B55 subfamily.

Defects in the 5' UTR of this gene may cause a rare form of autosomal dominant spinocerebellar ataxia 12.
