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

Protein phosphatase 2 is one of the four major Ser/Thr phosphatases, and it is implicated in the negative control of cell growth and division.

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

This gene encodes an alpha isoform of the regulatory subunit B55 subfamily.
