UniprotKB/SwissProt ID: F4IIM1 (F4IIM1)
Gene Name:
CSI1
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Regulator of the microtubular cytoskeleton (PubMed:22427339). Microtubule-associated protein essential for the functional association of cellulase synthase (CESA) complexes (CSCs) and cortical microtubules (PubMed:22190487, PubMed:22294619, PubMed:22751327, PubMed:23623553, PubMed:24368796). Promotes dynamics of CSCs in the plasma membrane (PubMed:20616083, PubMed:21150290, PubMed:22190487, PubMed:22294619, PubMed:22751327, PubMed:23623553, PubMed:24368796). Regulates primary cell wall biosynthesis and cellulose microfibrils organization (PubMed:20616083, PubMed:21150290, PubMed:23623553). Required for the regulation of root cell elongation/expansion (PubMed:20616083, PubMed:21150290, PubMed:22294619, PubMed:22427339, PubMed:7743935). Necessary for the formation of ovules, pollen cell wall morphogenesis and pollen tube development (PubMed:22294619). Involved in anther dehiscence, via dehydration-induced microtubule depolymerization and reorganization. May play a role in early gynoecial development (PubMed:22427339) Target of the cellulase synthase (CESA) complexes (CSCs) trafficking inhibitor CESTRIN, which reduces cellulose content and alters anisotropic growth of hypocotyls; CESTRIN treatment inhibits the dynamics of CSCs
