Functioni

Plays an important role in the control of DNA replication, maintenance of replication fork stability, maintenance of genome stability throughout normal DNA replication and in the regulation of the circadian clock. Involved in the determination of period length and in the DNA damage-dependent phase advancing of the circadian clock. Negatively regulates CLOCK|NPAS2-ARTNL/BMAL1|ARTNL2/BMAL2-induced transactivation of PER1 possibly via translocation of PER1 into the nucleus. Forms a complex with TIPIN and this complex regulates DNA replication processes under both normal and stress conditions, stabilizes replication forks and influences both CHEK1 phosphorylation and the intra-S phase checkpoint in response to genotoxic stress. Timeless promotes TIPIN nuclear localization. Involved in cell survival after DNA damage or replication stress. May be specifically required for the ATR-CHEK1 pathway in the replication checkpoint induced by hydroxyurea or ultraviolet light. May also play an important role in epithelial cell morphogenesis and formation of branching tubules.4 Publications

Interactioni

Subunit structurei

Homodimer or homomultimer (By similarity). Component of the circadian core oscillator, which includes the CRY proteins, CLOCK or NPAS2, ARTNL/BMAL1 or ARTNL2/BMAL2, CSKN1D and/or CSNK1E, TIMELESS, and the PER proteins. Interacts directly with PER2; the interaction with PER2 is via its second PAS domain. Interacts directly with PER1 and PER3 (By similarity). Interacts with CRY2, CHEK1, ATR and ATRIP (PubMed:15798197). Interacts with CRY1 (By similarity). Interacts with CLSPN (PubMed:17141802). Interacts with TIPIN (PubMed:17116885, PubMed:17102137, PubMed:17296725). Interacts with DDX11; this interaction increases recruitment of both proteins onto chromatin in response to replication stress induction by hydroxyurea (PubMed:20124417).By similarity7 Publications
