NFBD1, a Novel Nuclear Protein with Signature Motifs of FHA and BRCT, and an Internal 41-Amino Acid Repeat Sequence, Is an Early Participant in DNA Damage Response

Abstract excerpt

Efficient repair of DNA double-strand breaks depends on the intact signaling cascade, comprising molecules involved in DNA damage signal pathways and checkpoints. Budding yeast Rad9 (scRad9) is required for activation of scRad53 (mammalian homolog Chk2) and transduction of the signal further downstream in this pathway. In the search for a mammalian homolog, three proteins in the human data base, including BRCA1,...
