CORD2 is a member of a novel and plant specific family of microtubule associated proteins. CORD1 binds microtubules via a conserved protein domain shared among family members.
KRP2 is a CDK (cyclin-dependent kinase) inhibitor (CKI), negative regulator of cell division. The KRP2 protein abundance is regulated by proteolysis through CDKB1;1 phosphorylation.
MYC1 is MYC-related protein with a basic helix-loop-helix motif at the C-terminus and a region similar to the maize B/R family at the N-terminus. It is important regulator of trichome and root hair initiation.
GR1 is induced in response to ionizing radiation. May be involved in DNA damage-induced growth arrest. Protein sequence contains a PEST destruction box.
