Structural highlights
Function
[2A5G_HUMAN] The B regulatory subunit might modulate substrate selectivity and catalytic activity, and also might direct the localization of the catalytic enzyme to a particular subcellular compartment. The PP2A-PPP2R5C holoenzyme may specifically dephosphorylate and activate TP53 and play a role in DNA damage-induced inhibition of cell proliferation. PP2A-PPP2R5C may also regulate the ERK signaling pathway through ERK dephosphorylation.[1] [2] [CRBG1_HUMAN] May function as suppressor of malignant melanoma. It may exert its effects through interactions with the cytoskeleton.
