NCBI Protein Information
KIP-related protein 2
NCBI Summary
Kip-related protein (KRP) gene, encodes CDK (cyclin-dependent kinase) inhibitor (CKI), negative regulator of cell division. A member of seven KRP genes found in Arabidopsis thaliana. Differential expression patterns for distinct KRPs were revealed by in situ hybridization. Gene was isolated from a yeast two hybrid screen as an interacting protein of CDC2A. Recombinant protein has a strong kinase inhibitor activity in vitro. Transcript is expressed in all tissues examined but is differentially distributed from ICK1. Controls the onset of the endoreduplication cycle through inhibition of CDKA;1. The KRP2 protein abundance is regulated by proteolysis through CDKB1;1 phosphorylation.

UniProt Comments
Binds and inhibits CYCD2-1/CDKA-1 complex kinase activity. Regulates cell division which is crucial for plant growth, development and morphogenesis. May regulate early lateral root initiation by blocking the G1/S phase transition. Controls the mitosis-to-endocycle transition and the onset of the endoreduplication cycle during leaf development through inhibition of mitotic CDKA-1 kinase complexes. Specifically targets CDKA-1.
