This entry represents the C-terminal domain found in Phosphorylase b kinase regulatory alpha and beta subunits, which control the catalytic activity of the Phosphorylase kinase catalytic gamma subunit. this domain has been proposed as the second calcineurin B-like (CBL-2) domain containing a gamma subunit-binding site [1,2].
