General annotation (Comments)

Function

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. Probably recognizes and binds to phosphorylated target proteins. Involved in the degradation of cyclin E, NOTCH1 released notch intracellular domain (NICD), and probably PSEN1. Ref.3 Ref.8

Subunit structure

Component of the SCF(FBXW7) complex consisting of CUL1, RBX1, SKP1A and FBXW7. Interacts with PSEN1, cyclin E, NOTCH1 NICD, NOTCH4 NICD and SKP1A. Ref.3 Ref.8 Ref.4

Subcellular location

Nucleus By similarity.

Tissue specificity

Isoform 1 is widely expressed. Isoform 4 is expressed in brain. Ref.4

Post-translational modification

Phosphorylated upon DNA damage, probably by ATM or ATR. Ref.9

Sequence similarities

Contains 1 F-box domain.

Contains 7 WD repeats.

Also known as: Archipelago beta; 69K;

The sequence of this isoform differs from the canonical sequence as follows:
     1-80: Missing.
     81-166: NNRFISVDED...LSSPFYTKTT → MCVPRSGLIL...FYGTLKMIFY
Isoform 3 (identifier: Q969H0-3)

The sequence of this isoform differs from the canonical sequence as follows:
     1-166: MNQELLSVGS...LSSPFYTKTT → VLILSCICLY...FYGTLKMIFY
Note: Incomplete sequence.
Isoform 4 (identifier: Q969H0-4)

Also known as: Hippocampal;

The sequence of this isoform differs from the canonical sequence as follows:
     1-118: Missing.
     119-167: DQESDDFDQS...SSPFYTKTTK → MSKPGKPTLN...AQGLPFCRRR
