Studying the core circuitry of pluripotency by selective isolation of chromatin-associated proteins


ABSTRACT: Here we have developed a method to identify chromatin-bound partners of a protein of interest by selective isolation of chromatin-associated proteins (SICAP) followed by mass spectrometry. We applied SICAP to identify chromatin-binding proteins associated to Oct4, Sox2 and Nanog in mouse embryonic stem (ES) cells.

Maintenance of pluripotency is regulated by a network of transcription factors coordinated by Oct4, Sox2, and Nanog (OSN), yet a systematic investigation of the composition and dynamics of the OSN protein network specifically on chromatin is still missing. Here we have developed a method combining ChIP with selective isolation of chromatin-associated proteins (SICAP) followed by mass spectrometry to identify chromatin-bound partners of a protein of interest. ChIP-SICAP in mouse embryonic stem ce  ...[more]
