NCBI Protein Information
F-box/RNI-like superfamily protein
NCBI Summary
AtSKP2;1 is a homolog of human SKP2, the human F-box protein that recruits E2F1. Contains an F-box motif at the N-terminal region and a C-terminal Leu-rich repeat domain. Forms part of an E3-ubiquitin-ligase SCF (Skp1, cullin, F-box) complex and recruits phosphorylated AtE2Fc, a transcriptional factor that might play a role in cell division and during the transition from skotomorphogenesis to photomorphogenesis. AtSKP2;1 (At1g21410) and AtSKP2;2 (At1g77000) may be duplicated genes.

UniProt Comments
Component of SCF(SKP2A) E3 ubiquitin ligase complexes, which mediate the ubiquitination and subsequent proteasomal degradation of target proteins (including cell cycle repressors). Acts as an auxin receptor. Regulates the stability of the transcription factors E2FC and DPB, repressors of cell proliferation. Confers increase tolerance to osmotic stress by promoting cell division, especially in meristems. Promotes the formation of lateral root primordia.
