ESP — Brassica oleracea

Summary

BoESP (ESP, AESP1, RSW4) on chromosome 1 of cabbage encodes a separin-family protease with thiol endopeptidase activity, containing a Peptidase_C50 domain and TPR_ESP repeats. The gene is associated with chromosome separation, upregulation of sister chromatid cohesion, meiotic chromosome separation, and cytokinesis by cell plate formation. It is linked to glucosinolate breakdown and anabolism, endosperm and embryo development, polar cell growth, cell growth anisotropy, root morphology, and plant morphogenesis. The encoded protein localises to microtubules and is associated with vesicle transport, exocytosis, and response to glucose. Studies of related genes in other species link the family to herbivore defense, glucosinolate hydrolysis, meiosis, cytokinesis, gravitropic response, and embryo development.
