Reaserch advanced in Calreticulins(CRT) of higher plants
Abstract:Calreticulin is an abundant Ca2+-binding protein predominantly located in the endoplasmic reticulum(ER) of higher plants.All plant CRTs identified consist of three distinct structural domains linked to different functions so far. There were plenty of researches showed that CRT was a multifunctional protein such as a chaperon and modulator of Ca2+ signaling in ER, a key player in plant growth and development, a powerful regulator in plant responses to various stresses.The structure, isoforms and biological function were reviewed in this paper.
