Histone H1-like DNA-binding protein involved in the organization and segregation of kinetoplast DNA (kDNA). The mitochondrial DNA of kinetoplastid protozoa consists of about 5,000 minicircles and 20 to 30 maxicircles. These circular DNAs are held together by catenation into a highly organized compact disk structure referred to as a kinetoplast DNA (kDNA) network. Binds preferentially to a specific fragment of minicircle DNA and is able to compact kDNA networks through DNA charge neutralization and condensation. Associates with the kinetoplast DNA network. Present both within the kDNA disk and in the mitochondrial matrix at opposite edges of the kDNA disk. Belongs to the KAP family.
