[5] In the plant Arabidopsis thaliana a similar enzyme is encoded by the RCN1 gene (At1g25490).

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

This gene encodes an alpha isoform of the constant regulatory subunit A.

[7] PPP2R1A has been shown to interact with: RCN1 At1g25490 is one of three genes in Arabidopsis encoding Phosphoprotein Phosphatase 2A Regulatory Subunit A (PP2Aa).
