Summary: Predicted to enable NF-kappaB binding activity; p53 binding activity; and protein homodimerization activity. Acts upstream of or within several processes, including embryo development; heart development; and response to ionizing radiation. Predicted to be located in cell junction and cytosol. Predicted to be active in nucleus. Predicted to colocalize with perinuclear region of cytoplasm. Is expressed in several structures, including alimentary system; brain; respiratory system; sensory organ; and urinary system. Used to study chromosome 1q41-q42 deletion syndrome. Orthologous to human TP53BP2 (tumor protein p53 binding protein 2). [provided by Alliance of Genome Resources, Apr 2025]

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.
