To demonstrate that RGP-family genes have functions that are significantly divergent from those of RanBP2, Bork and his co-workers examined the subcellular localization of one of the RGP-family isoforms. In contrast to RanBP2...Green tea extract shows promise as an anti-cancer agent, UCLA study finds
