Automated description from the Alliance of Genome Resources (Release 3.1.1)
Exhibits damaged DNA binding activity; methylated histone binding activity; and telomeric DNA binding activity. Involved in double-strand break repair via nonhomologous end joining; negative regulation of double-strand break repair via homologous recombination; and positive regulation of isotype switching. Localizes to DNA repair complex; chromosome; and nuclear body. Predicted to colocalize with chromosome, telomeric region. Is expressed in ileum; lung; metanephros; nervous system; and sensory organ. Orthologous to human TP53BP1 (tumor protein p53 binding protein 1).
