Therefore, the α-subunit can be considered the regulatory subunit of the trimer.

There are two known regulatory subunits for p110γ:

There is no homologue for the p80 katanin regulatory subunit.

This regulatory subunit is a small protein of 79 to 150 residues.

The protein encoded by this gene is one of the regulatory subunits.

These is no evidence for selective association between p110α, p110β or p110δ for any particular regulatory subunit.

The catalytic subunit can from complexes with various regulatory subunits.

These regulatory subunits play an important role in substrate specificity as well as compartmentalization.

This gene encodes a constant regulatory subunit of protein phosphatase 2.

In human cells Vps34 associates with a regulatory subunit, p150.
