ISWI

ISWI (I 내려 인기쉽게) is a chromatin-remodeling complex that helps organize DNA within the cell nucleus. It uses energy from ATP (a cellular fuel) to shift, assemble, or disassemble nucleosomes—structures made of DNA wrapped around proteins. This activity influences how accessible certain genes are, thereby controlling gene expression and DNA repair. By remodeling chromatin, ISWI plays a vital role in regulating cellular processes like development, differentiation, and response to environmental signals, ensuring the genome functions properly and adaptively.
