Anti-SMC4

SMC (Structural maintenance of chromosomes) proteins are part of the cohesin and condensin multisubunit complexes that play a critical role in chromosome organization, segregation, gene regulation, and DNA repair. The core condensin complex includes a heterodimer of SMC2 and SMC4 that functions to create positively supercoiled loops for chromatin condensation and metaphase chromatid shaping. A function for condensin in the DNA damage checkpoint response and gene repression has also been suggested. Protein function: Central component of the condensin complex, a complex required for conversion of interphase chromatin into mitotic-like condense chromosomes. The condensin complex probably introduces positive supercoils into relaxed DNA in the presence of type I topoisomerases and converts nicked DNA into positive knotted forms in the presence of type II topoisomerases.
