RiceNetDB is currently the most comprehensive regulatory database on Oryza Sativa
based on genome annotation. It was displayed in three levels: GEM, PPIs and GRNs
to facilitate biomolecular regulatory analysis and gene-metabolite mapping.
Cell membrane polyamine/proton symporter involved in the polyamine uptake in cells. Possesses high affinity for spermidine and lower affinity for spermine and putrescine. Transports paraquat, a polyamine analog, and thus confers sensitivity to this chemical which is used as a herbicide.
