RNI-like superfamily protein
NCBI Summary
AtSKP2;2 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. AtSKP2b may also be involved in the degradation of KRP1/ICK1, a CDK inhibitor.

UniProt Comments
Component of SCF(SKP2B) E3 ubiquitin ligase complexes, which mediate the ubiquitination and subsequent proteasomal degradation of the cyclin-dependent kinase inhibitor KRP1. Does not interact with auxin.
