What is the function of this protein?
Component of the MMS22L-TONSL complex, a complex that promotes homologous recombination-mediated repair of double-strand breaks (DSBs) at stalled or collapsed replication forks (PubMed:21055983, PubMed:21055984, PubMed:21055985, PubMed:21113133, PubMed:26527279, PubMed:27797818, PubMed:29478807, PubMed:27338793, PubMed:30773278).  The MMS22L-TONSL complex is required to maintain genome integrity during DNA replication (PubMed:21055983, PubMed:21055984, PubMed:21055985).  It mediates the assembly of RAD51 filaments on single-stranded DNA (ssDNA): the MMS22L-TONSL complex is recruited to DSBs following histone replacement by histone chaperones and eviction of the replication protein A complex (RPA/RP-A) from DSBs (PubMed:21055983, PubMed:21055984, PubMed:21055985, PubMed:27797818, PubMed:29478807).  Following recruitment to DSBs, the TONSL-MMS22L complex promotes recruitment of RAD51 filaments and subsequent homologous recombination (PubMed:27797818, PubMed:29478807).  Within the complex, TONSL acts as histone reader, which recognizes and binds newly synthesized histones following their replacement by histone chaperones (PubMed:29478807, PubMed:27338793).  Specifically binds histone H4 lacking methylation at 'Lys-20' (H4K20me0) and histone H3. 1 (PubMed:27338793).
What are the official names of this protein?
Tonsoku-like protein, Inhibitor of kappa B-related protein, I-kappa-B-related protein, IkappaBR, NF-kappa-B inhibitor-like protein 2, Nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor-like 2.
What is the protein family that this protein belongs to?
Belongs to the Tonsoku family.
What are the subcellular locations of this protein?
Nucleus. Chromosome. Cytoplasm. Note=Mainly nuclear (PubMed:21055983, PubMed:21055984). Localizes to DNA damage sites, accumulates at stressed replication forks (PubMed:21055983, PubMed:21055984, PubMed:26527279, PubMed:27338793). Recruited to stalled or collapsed replication forks following histone replacement by histone chaperones ASF1A and the CAF-1 complex: TONSL acts as histone reader that recognizes and binds newly synthesized histones (PubMed:29478807).
