The function of Ensembl gene identifier ENSG00000109805 (NCAPG, non-SMC condensin I complex subunit G) is as follows. Regulatory subunit 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. .
