Identification of CCR4C as a chloroplast-localized NADP(H) phosphatase regulating NAD(P)(H) balance in Arabidopsis

Proceedings of the National Academy of Sciences, Volume 122, Number 42, October 2025.
Significance This study identifies CCR4C as a chloroplast-localized NAD(P)(H) phosphatase in Arabidopsis, distinct from other CCR4 family members involved in mRNA deadenylation. CCR4C modulates NAD(P)(H) levels by converting NADP(H) to NAD(H), thus…
