<i>Kr</i> regulation: Bcd and Hb TF binding; effect of bound state on transcription; translation; decay (mRNA and protein).

KrYx is the bound state of transcription factor Y; B is Bcd protein; MKr is Kr mRNA. Kr regulation: Bcd and Hb TF binding; effect of bound state on transcription; translation; decay (mRNA and protein).KrYx 为转录因子（transcription factor）Y的结合态；B 为Bcd蛋白；MKr 为Kr信使RNA（mRNA）。Kr的调控过程包括Bcd与Hb转录因子的结合、结合态对转录的调控作用、翻译过程以及信使RNA与蛋白质的降解过程。
