機能Component of some SCF (SKP1-cullin-F-box) protein ligase complex that plays a central role in G1 arrest following DNA damage. Specifically recognizes phosphorylated cyclin-D1 (CCND1), promoting its ubiquitination and degradation by the proteasome, resulting in G1 arrest. May act as a tumor suppressor.
組織特異性Highly expressed in brain. Expressed at moderate levels in most tissues, except bone marrow.
パスウェイProtein modification; protein ubiquitination.
配列類似性Belongs to the FBXO31 family. Contains 1 F-box domain.
発生段階Expression is cell-cycle regulated, and peaks at late G2 to early G1 phase (at protein level).
翻訳後修飾Phosphorylation at Ser-278 by ATM following gamma-irradiation results in its stabilization.
