This entry includes GIP1 and GIP1L from plants. GIP1 may act as a coactivator that regulates transcription factors involved in lateral organ development of plants, such as bZIP transcription factors and LBD18 [ 1 , 2 ]. The function of GIP1L is not clear.

1. GIP1 may act as a coactivator that enhances transcriptional activity of LBD18 in Arabidopsis. J. Plant Physiol. 171, 14-8
2. GIP1 protein is a novel cofactor that regulates DNA-binding affinity of redox-regulated members of bZIP transcription factors involved in the early stages of Arabidopsis development. Protoplasma 252, 867-83
