Abstract
Dysregulation of epigenetic mechanisms at key moments in human development can dramatically impact neuronal migration and cell fate determination. In Autism Spectrum Disorder (ASD), modification of specific histone tail residues promotes recruitment of an adaptor protein complex, human Polycomb Repressive Complex 1 (PRC1), which increases chromatin compaction via mono-ubiquitination of histone H2A at lysine 119. We sought to establish and optimize an immunofluorescent method for the detection and visualization of PRC1.6 interactors ADNP and POGZ in neural tissues. Additionally, we characterized expression of ADNP/POGZ-containing PRC1.6 across neurodevelopment in embryonic stem cells, maturing primary cortical neurons, and adult mouse brain.
