Identification and Functional Characterization of a New Splicing Variant of EZH2 in the Central Nervous System.

ABSTRACT: EZH2 plays vital roles in epigenetic regulation, neuronal development and cancer progression. Here a novel EZH2 variant, namely EZH2-X9 (X9 for short) resulting from alternative splicing, was isolated, identified and functionally characterized. X9 was highly expressed in the brains of SD rats, indicating a potentially distinguished role in the central nervous system (CNS). Owing to a transcript profiling, X9 was enriched in multiple brain regions at very early stage of life. Immunostaining validated the presence of the protein form of X9, which was localized similarly with the wild-type form, EZH2-WT. To investigate the functional consequence of X9, genetic intervention was performed in PC-12 cell line, a classic cellular model for neuronal development. It revealed that the depletion of ei
