ESP — Brassica oleracea

Summary

BoESP, encoded by the cabbage gene BOLC102_C07P057210.1 on chromosome 7, is a thiol endopeptidase (protease) belonging to the peptidase C50 family and containing SEPARIN core and TPR_ESP domains. In cabbage, BoESP is associated with chromosome separation, meiotic chromosome separation, upregulation of sister chromatid cohesion, glucosinolate breakdown and anabolism, exocytosis, vesicle transport, cytokinesis by cell plate formation, endosperm and embryo development, response to glucose, cell polarization, and polar cell growth. It localizes to microtubules. Phenotypic associations include cell growth anisotropy, plant morphogenesis, chromosome disjunction, root morphology, and embryo lethality. Studies of related genes in other species link the ESP family to herbivore defense, glucosinolate hydrolysis, meiosis, cytokinesis, gravitropic response, cell polarity, and embryo development.
