What's a GeneRIF?

ATR activation is regulated by dimerization of ATR activating proteins.
Title: ATR activation is regulated by dimerization of ATR activating proteins.
ETAA1 may have an important role in protecting against genome instability arising from incompletely duplicated DNA via regulatory control of its ATR-stimulating potential
Title: Regulation of ETAA1-mediated ATR activation couples DNA replication fidelity and genome stability.
ETAA1 regulates mitotic ATR signaling and is required for proper chromosome alignment during metaphase and for a fully functional spindle assembly checkpoint response.
Title: Quantitative phosphoproteomics reveals mitotic function of the ATR activator ETAA1.
ETAA1 and TOPBP1 contain a predicted coiled-coil motif that is required for ATR activation in vitro and in cells. Mutation of the predicted coiled coils does not alter AAD oligomerization but does impair binding of the AADs to ATR.
Title: Common motifs in ETAA1 and TOPBP1 required for ATR kinase activation.
These our data suggest that ETAA1 is a new ATR activator involved in replication checkpoint control.
Title: RPA-Binding Protein ETAA1 Is an ATR Activator Involved in DNA Replication Stress Response.
results reveal that ETAA1 is a novel RPA-interacting protein that promotes restart of stalled replication forks.
Title: Ewing Tumor-associated Antigen 1 Interacts with Replication Protein A to Promote Restart of Stalled Replication Forks.
ETAA1 acts as a direct ATR serine-threonine kinase protein activator
Title: ETAA1 acts at stalled replication forks to maintain genome integrity.
that parallel TopBP1- and ETAA1-mediated pathways underlie ATR activation and that their combined action is essential for coping with replication stress
Title: Activation of the ATR kinase by the RPA-binding protein ETAA1.
results suggest that ETAA16 may function as a tumour-specific cell surface antigen in Ewing's family of tumors

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
