Seems to control heterocyst pattern formation through intercellular signaling mechanisms. In Anabaena filaments every 10th vegetative cell terminally differentiates into a heterocyst specialized for nitrogen fixation. Seems to inhibit the formation of adjacent heterocysts. Inhibits the DNA-binding of HetR.<ref>PMID:11274121</ref> <ref>PMID:15051891</ref> <ref>PMID:9794762</ref>
