Project description:The protein PURA binds to DNA and RNA and has been suggested to be implicated in different cellular functions. Here, we show that PURA predominantly resides in the cytoplasm, where it binds to a large set of transcripts.

Project description:PURA syndrome is a rare neurodevelopmental disorder caused by heterozygous de novo mutations in the PURA gene, leading to intellectual disability, hypotonia, and epilepsy. While the molecular functions of PURA have been partially elucidated, its role in human neural development remains unclear. We used PURA-knockout (KO) human induced pluripotent stem cells (iPSCs) and isogenic controls to generate 2D neural progenitor cultures and 3D cerebral organoids.Transcriptomic profiling identified PURA-regulated RNAs critical for early neuronal development.

Project description:Here, we show that PURA predominantly resides in the cytoplasm, where it binds to a large set of transcripts. Many of these transcripts change abundance in response to PURA depletion, in parts reflected in altered protein expression levels. A closer inspection of the regulated proteins indicates a role of PURA in immune responses, mitochondrial function, autophagy and processing (P)-body activity.
