CC -!- FUNCTION: Essential component of the SCF (SKP1-CUL1-F-box protein)
CC ubiquitin ligase complex, which mediates the ubiquitination of proteins
CC involved in cell cycle progression, signal transduction and
CC transcription. In the SCF complex, serves as an adapter that links the
CC F-box protein to CUL1. The functional specificity of the SCF complex
CC depends on the F-box protein as substrate recognition component.
CC SCF(BTRC) and SCF(FBXW11) direct ubiquitination of CTNNB1 and
CC participate in Wnt signaling. SCF(FBXW11) directs ubiquitination of
CC phosphorylated NFKBIA. SCF(BTRC) directs ubiquitination of NFKBIB,
CC NFKBIE, ATF4, SMAD3, SMAD4, CDC25A, FBXO5, CEP68 and probably NFKB2.
CC SCF(SKP2) directs ubiquitination of phosphorylated CDKN1B/p27kip and is
CC involved in regulation of G1/S transition. SCF(SKP2) directs
CC ubiquitination of ORC1, CDT1, RBL2, ELF4, CDKN1A, RAG2, FOXO1A, and
CC probably MYC and TAL1. SCF(FBXW7) directs ubiquitination of cyclin E,
CC NOTCH1 released notch intracellular domain (NICD), and probably PSEN1.
CC SCF(FBXW2) directs ubiquitination of GCM1. SCF(FBXO32) directs
CC ubiquitination of MYOD1. SCF(FBXO7) directs ubiquitination of BIRC2 and
CC DLGAP5. SCF(FBXO33) directs ubiquitination of YBX1. SCF(FBXO11) directs
CC ubiquitination of BCL6 and DTL but does not seem to direct
CC ubiquitination of TP53. SCF(BTRC) mediates the ubiquitination of NFKBIA
CC at 'Lys-21' and 'Lys-22'; the degradation frees the associated NFKB1-
CC RELA dimer to translocate into the nucleus and to activate
CC transcription. SCF(CCNF) directs ubiquitination of CCP110. SCF(FBXL3)
CC and SCF(FBXL21) direct ubiquitination of CRY1 and CRY2. SCF(FBXO9)
CC directs ubiquitination of TTI1 and TELO2. SCF(FBXO10) directs
CC ubiquitination of BCL2. {ECO:0000250|UniProtKB:P63208}.
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC -!- SUBUNIT: Interacts with KDM2B, forming heterodimers (By similarity).

CC heterodimeric complex to form a homotetrameric polycomb repression
CC complex 1 (PRC1.1) (By similarity). Component of multiple SCF (SKP1-

CC Component of the SCF(FBXO25) complex containing FBXO25. Component of
CC the SCF(FBXO33) complex containing FBXO33. Component of the probable
CC SCF(FBXO4) complex containing FBXO4. Component of the SCF(FBXO44)
CC complex, composed of SKP1, CUL1 and FBXO44. Component of the SCF(BTRC)
CC complex, composed of SKP1, CUL1 and BTRC. This complex binds

CC SKP1 and FBXO2. Component of a SCF(SKP2)-like complex containing CUL1,
CC SKP1, TRIM21 and SKP2. Component of the SCF(FBXO17) complex, composed
CC of SKP1, CUL1 and FBXO17. Component of the SCF(FBXO27) complex,
CC composed of SKP1, CUL1 and FBXO27. Component of the SCF(CCNF) complex
CC consisting of CUL1, RBX1, SKP1 and CCNF. Component of the SCF(FBXL3)
CC complex composed of CUL1, SKP1, RBX1 and FBXL3. Component of the
CC SCF(FBXL21) complex composed of CUL1, SKP1, RBX1 and FBXL21. Component
CC of the SCF(FBXO9) composed of CUL1, SKP1, RBX1 and FBXO9. Component of
CC the SCF(FBXW7) composed of CUL1, SKP1, RBX1 and FBXW7. Interacts with
CC CEP68. Interacts with NOTCH2 and FBXW15 (By similarity). The SKP1-KDM2A
CC and SKP1-KDM2B complexes interact with UBB (By similarity).
CC {ECO:0000250|UniProtKB:P63208, ECO:0000250|UniProtKB:Q9WTX5}.
CC -!- PTM: Undergoes autophagy-mediated degradation in the liver in a time-
CC dependent manner. {ECO:0000250|UniProtKB:Q9WTX5}.
CC -!- SIMILARITY: Belongs to the SKP1 family. {ECO:0000305}.
