Function

Plays an important role in the control of DNA replication, maintenance of replication fork stability, maintenance of genome stability throughout normal DNA replication, DNA repair and in the regulation of the circadian clock (PubMed:17141802, PubMed:17296725, PubMed:23359676, PubMed:23418588, PubMed:26344098, PubMed:31138685, PubMed:32705708, PubMed:35585232, PubMed:9856465). Required to stabilize replication forks during DNA replication by forming a complex with TIPIN: 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 (PubMed:17141802, PubMed:17296725, PubMed:23359676, PubMed:35585232). During DNA replication, inhibits the CMG complex ATPase activity and activates DNA polymerases catalytic activities, coupling DNA unwinding and DNA synthesis (PubMed:23359676). TIMELESS promotes TIPIN nuclear localization (PubMed:17141802, PubMed:17296725). Plays a role in maintaining processive DNA replication past genomic guanine-rich DNA sequences that form G-quadruplex (G4) structures, possibly together with DDX1 (PubMed:32705708). Involved in cell survival after DNA damage or replication stress by promoting DNA repair (PubMed:17141802, PubMed:17296725, PubMed:26344098, PubMed:30356214). In response to double-strand breaks (DSBs), accumulates at DNA damage sites and promotes homologous recombination repair via its interaction with PARP1 (PubMed:26344098, PubMed:30356214, PubMed:31138685). May be specifically required for the ATR-CHEK1 pathway in the replication checkpoint induced by hydroxyurea or ultraviolet light (PubMed:15798197). Involved in the determination of period length and in the DNA damage-dependent phase advancing of the circadian clock (PubMed:23418588, PubMed:31138685). Negatively regulates CLOCK|NPAS2-ARTNL/BMAL1|ARTNL2/BMAL2-induced transactivation of PER1 possibly via translocation of PER1 into the nucleus (PubMed:31138685, PubMed:9856465). May play a role as destabilizer of the PER2-CRY2 complex (PubMed:31138685). May also play an important role in epithelial cell morphogenesis and formation of branching tubules (By similarity).

Notes

ab248557 is the carrier-free version of Anti-Timeless antibody [EPR5274(2)] ab133569.

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

For more information, read more on recombinant antibodies.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.

Activity summary

Timeless also known as timeless circadian regulator is a protein with a molecular mass of about 139 kDa. It plays an important role in the stabilization of the circadian rhythm in mammals. Timeless associates with other clock proteins and participates in the feedback loop that drives circadian oscillations influencing hormonal and metabolic pathways. Researchers find Timeless expression primarily in the suprachiasmatic nucleus of the brain the central circadian pacemaker but it is also present in peripheral tissues.

Biological function summary

The protein influences the circadian rhythm by interacting with CLOCK and BMAL1 forming part of a macromolecular complex. Timeless helps sustain the proper timing and expression of various genes influenced by the circadian rhythm ensuring an orderly and synchronized cellular process across tissues. Its interaction with other clock components regulates circadian-controlled pathways governing processes like sleep-wake cycles hormone release and cell metabolism.

Pathways

Timeless participates in the regulation of the circadian rhythm and the cell cycle. It interacts with PER1 and PER2 proteins central to the inhibition of the CLOCK/BMAL1 complex which plays a pivotal role in maintaining the circadian clock's precision. Timeless also interfaces with proteins involved in DNA damage response pathways promoting effective DNA repair during cell division and aligning cell cycle regulation with circadian rhythms.

Associated diseases and disorders

Timeless has been linked to cancer and sleep disorders. The protein's role in DNA repair and cell cycle control associates it with tumorigenesis when its function becomes dysregulated. Additionally disruptions in Timeless expression or function are connected to sleep phase disorders highlighting its involvement in maintaining proper circadian function. In cancer alterations in Timeless could lead to interactions with oncogenes or tumor suppressors potentially affecting cancer progression.
