== Function ==
[https://www.uniprot.org/uniprot/SKP2_HUMAN SKP2_HUMAN] Substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins involved in cell cycle progression, signal transduction and transcription. Specifically recognizes phosphorylated CDKN1B/p27kip and is involved in regulation of G1/S transition. Degradation of CDKN1B/p27kip also requires CKS1. Recognizes target proteins ORC1, CDT1, RBL2, MLL, CDK9, RAG2, FOXO1, UBP43, and probably MYC, TOB1 and TAL1. Degradation of TAL1 also requires STUB1. Recognizes CDKN1A in association with CCNE1 or CCNE2 and CDK2. Promotes ubiquitination and destruction of CDH1 in a CK1-Dependent Manner, thereby regulating cell migration.<ref>PMID:12435635</ref> <ref>PMID:11931757</ref> <ref>PMID:12840033</ref> <ref>PMID:12769844</ref> <ref>PMID:15342634</ref> <ref>PMID:16262255</ref> <ref>PMID:15949444</ref> <ref>PMID:16103164</ref> <ref>PMID:15668399</ref> <ref>PMID:16951159</ref> <ref>PMID:16581786</ref> <ref>PMID:17908926</ref> <ref>PMID:17962192</ref> <ref>PMID:22770219</ref>
