BAG4 — Cicer arietinum

Summary

LOC101496017 (CaBAG4) on chickpea chromosome 6 encodes a BAG family molecular chaperone regulator containing a BAG domain and a ubiquitin-like domain. The product is associated with protein binding and has been linked to the regulation of stomatal movement, positive regulation of potassium transport, protein membrane targeting, the transition from vegetative to reproductive phase, cell death, programmed cell death, and responses to cold and salinity. It localises to the endoplasmic reticulum, ER exit site, cytosol and nucleus. Associations with seed protein content, nitrogen content and stomatal movement have been noted. Studies of related genes in other species link the family to drought tolerance, salinity tolerance, nodulation, nitrogen fixation, photosynthesis, crop yield, early flowering, increased branching and early senescence.
