Single-stranded DNA-binding proteins form protective caps at the chromosome ends and their binding is important in the regulation of telomerase access to telomeres. This group of proteins is represented by POT1 proteins described in yeast, humans and other model organisms. Here we review recent findings obtained in Arabidopsis POT1-like paralogs, namely the observed diversity in their interaction features and corresponding functions.
