CPTC-TP53BP1-1 (CAB079980) Immunohistochemistry Immunofluorescence
CPTC-TP53BP1-1 (CAB079980) Uniprot ID: Q12888 Protein name: TP53B_HUMAN Full name: TP53-binding protein 1 Function: Double-strand break (DSB) repair protein involved in response to DNA damage, telomere dynamics and class-switch recombination (CSR) during antibody genesis (PubMed:12364621, PubMed:22553214, PubMed:23333306, PubMed:17190600, PubMed:21144835, PubMed:28241136). Plays a key role in the repair of double-strand DNA breaks (DSBs) in response to DNA damage by promoting non-homologous end joining (NHEJ)- mediated repair of DSBs and specifically counteracting the function of the homologous recombination (HR) repair protein BRCA1 (PubMed:22553214, PubMed:23727112, PubMed:23333306). In response to DSBs, phosphorylation by ATM promotes interaction with RIF1 and dissociation from NUDT16L1/TIRR, leading to recruitment to DSBs sites (PubMed:28241136). Recruited to DSBs sites by recognizing and binding histone H2A monoubiquitinated at 'Lys-15' (H2AK15Ub) and histone H4 dimethylated at 'Lys-20' (H4K20me2), two histone marks that are present at DSBs sites (PubMed:23760478, PubMed:28241136, PubMed:17190600). Required for immunoglobulin class-switch recombination (CSR) during antibody genesis, a process that involves the generation of DNA DSBs (PubMed:23345425). Participates in the repair and the orientation of the broken DNA ends during CSR (By similarity). In contrast, it is not required for classic NHEJ and V(D)J recombination (By similarity). Promotes NHEJ of dysfunctional telomeres via interaction with PAXIP1 (PubMed:23727112). Subcellular -

DNA Damage and Its Links to Neurodegeneration
Neuron Review DNA Damage and Its Links to Neurodegeneration Ram Madabhushi,1,2 Ling Pan,1,2 and Li-Huei Tsai1,2,* 1Picower Institute for Learning and Memory 2Department of Brain and Cognitive Sciences Massachusetts Institute of Technology, Cambridge, MA 02139, USA *Correspondence: [email protected] http://dx.doi.org/10.1016/j.neuron.2014.06.034 The integrity of our genetic material is under constant attack from numerous endogenous and exogenous agents. The consequences of a defective DNA damage response are well studied in proliferating cells, espe- cially with regards to the development of cancer, yet its precise roles in the nervous system are relatively poorly understood. Here we attempt to provide a comprehensive overview of the consequences of genomic instability in the nervous system. We highlight the neuropathology of congenital syndromes that result from mutations in DNA repair factors and underscore the importance of the DNA damage response in neural devel- opment. In addition, we describe the findings of recent studies, which reveal that a robust DNA damage response is also intimately connected to aging and the manifestation of age-related neurodegenerative dis- orders such as Alzheimer’s disease and amyotrophic lateral sclerosis.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

Zawia DEAN OF THE GRADUATE SCHOOL UNIVERSITY OF RHODE ISLAND 2015 ABSTRACT Fanconi anemia (FA) is a rare autosomal and X-linked recessive disorder, characterized by congenital abnormalities, pediatric bone marrow failure and cancer susceptibility. FA is caused by biallelic mutations in any one of 16 genes. The FA proteins function cooperatively in the FA-BRCA pathway to repair DNA interstrand crosslinks (ICLs). The monoubiquitination of FANCD2 and FANCI is a central step in the activation of the FA-BRCA pathway and is required for targeting these proteins to chromatin. -

DNA Damage Response and Cancer Therapeutics Through the Lens of the Fanconi Anemia DNA Repair Pathway Sonali Bhattacharjee* and Saikat Nandi*
Bhattacharjee and Nandi Cell Communication and Signaling (2017) 15:41 DOI 10.1186/s12964-017-0195-9 REVIEW Open Access DNA damage response and cancer therapeutics through the lens of the Fanconi Anemia DNA repair pathway Sonali Bhattacharjee* and Saikat Nandi* Abstract Fanconi Anemia (FA) is a rare, inherited genomic instability disorder, caused by mutations in genes involved in the repair of interstrand DNA crosslinks (ICLs). The FA signaling network contains a unique nuclear protein complex that mediates the monoubiquitylation of the FANCD2 and FANCI heterodimer, and coordinates activities of the downstream DNA repair pathway including nucleotide excision repair, translesion synthesis, and homologous recombination. FA proteins act at different steps of ICL repair in sensing, recognition and processing of DNA lesions. The multi-protein network is tightly regulated by complex mechanisms, such as ubiquitination, phosphorylation, and degradation signals that are critical for the maintenance of genome integrity and suppressing tumorigenesis. Here, we discuss recent advances in our understanding of how the FA proteins participate in ICL repair and regulation of the FA signaling network that assures the safeguard of the genome. We further discuss the potential application of designing small molecule inhibitors that inhibit the FA pathway and are synthetic lethal with DNA repair enzymes that can be used for cancer therapeutics. Keywords: DNA repair, Fanconi Anemia (FA) signaling network, DNA damage response, Cancer therapeutics, Synthetic lethality, Combination Therapy Genomic instability, Interstrand crosslink (ICL), Homologous recombination, Translesion synthesis Background Additional clinical features included microcephaly, vitiligo Fanconi Anemia (FA), a rare genetic cancer-susceptibility and hypoplasia of the testes [8].
