Abstract

This entry represents a group of plant proteins, including NIP1/2 and NIPL1/2 from Arabidopsis. NIP1 and NIP2 are integral thylakoid membrane proteins that contain three N-terminal transmembrane helixes and a C-terminal RING domain. NIP1/2 interact with plastid phage-type RNA polymerase RPOTmp and fixes RPOTmp on the stromal side of the thylakoid membrane [ 1 ]. The function of NIPL1/2 is not clear.
