| AT2G33460 | ROP-interactive CRIB motif-containing protein 1 (RIC1); FUNCTIONS IN: protein binding; INVOLVED IN: cell morphogenesis, pollen tube growth, cellulose microfibril organization, cytoplasmic microtubule organization; LOCATED IN: cortical microtubule, transverse to long axis, apical plasma membrane; EXPRESSED IN: 11 plant structures; EXPRESSED DURING: L mature pollen stage, M germinated pollen stage, 4 anthesis, C globular stage, petal differentiation and expansion stage; CONTAINS InterPro DOMAIN/s: PAK-box/P21-Rho-binding (InterPro:IPR000095); BEST Arabidopsis thaliana protein match is: ROP-interactive CRIB motif-containing protein 3 (TAIR:AT1G04450.1); Has 393 Blast hits to 355 proteins in 75 species: Archae - 0; Bacteria - 15; Metazoa - 105; Fungi - 14; Plants - 178; Viruses - 2; Other Eukaryotes - 79 (source: NCBI BLink). encodes a member of a novel protein family that contains contain a CRIB (for Cdc42/Rac-interactive binding) motif required for their specific interaction with GTP-bound Rop1 (plant-specific Rho GTPase). Interacts with Rop1 and is involved in pollen tube growth and function. Protein most similar to RIC3(family subgroup III). RIC1 is localized to the apical region of the plasma membrane in pollen tube and mutation analyses indicate that this localization is dependent on ROP1 binding. Gene is expressed in all tissues examined.Analysis of overexpression and loss of function mutants indicates a role in cortical microtubule organization during pavement cell morphogenesis.
