The Cat Eye Syndrome Chromosome Region Candidate 2 (CECR2) is the regulatory subunit of the ATP-dependent CERF-1 and CERF-5 ISWI chromatin remodeling complexes that modulate nucleosome spacing and DNA accessibility during replication and transcription.[1][2][3][4]. CECR2 also plays a key role in the DNA damage repair response, as it inhibits γ-H2AX activity.[5]. CECR2 is involved in various processes during development, including embryogenesis and spermatogenesis.[6][7]. Recent studies have identified CECR2 as an epigenetic regulator of NF-kB pro-inflammatory gene expression through the recognition of acetylated RelA and driving breast cancer metastasis.[8]
