CC -!- FUNCTION: Substrate-recognition component of the SCF (SKP1-CUL1-F-box
CC protein)-type E3 ubiquitin ligase complex. {ECO:0000250}.
CC -!- SUBUNIT: Part of a SCF (SKP1-cullin-F-box) protein ligase complex.
CC Interacts with SKP1 and CUL1 (By similarity). {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q8BK26-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q8BK26-2; Sequence=VSP_011348, VSP_011349;
CC -!- TISSUE SPECIFICITY: Expressed in brain, liver, pancreas and adipose
CC tissue (at protein level). Widely expressed.
CC {ECO:0000269|PubMed:18203720}.
CC -!- DEVELOPMENTAL STAGE: Strong expression in embryos. Maximally expressed
CC in brain during embryonic development but declined thereafter.
CC {ECO:0000269|PubMed:18203720}.
