We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| + | [https://www.uniprot.org/uniprot/CXXC5_HUMAN CXXC5_HUMAN] May indirectly participate in activation of the NF-kappa-B and MAPK pathways. Acts as a mediator of BMP4-mediated modulation of canonical Wnt signaling activity in neural stem cells (By similarity). Required for DNA damage-induced ATM phosphorylation, p53 activation and cell cycle arrest. Involved in myelopoiesis. Transcription factor. Binds to the oxygen responsive element of COX4I2 and represses its transcription under hypoxia conditions (4% oxygen), as well as normoxia conditions (20% oxygen) (PubMed:23303788). May repress COX4I2 transactivation induced by CHCHD2 and RBPJ (PubMed:23303788).<ref>PMID:19182210</ref> <ref>PMID:19557330</ref> <ref>PMID:23303788</ref> | ||

| + | The CXXC domain, first identified as the reader of unmodified CpG dinucleotide, plays important roles in epigenetic regulation by targeting various activities to CpG islands. Here we systematically measured and compared the DNA-binding selectivities of all known human CXXC domains by different binding assays, and complemented the existing function-based classification of human CXXC domains with a classification based on their DNA selectivities. Through a series of crystal structures of CXXC domains with DNA ligands, we unravel the molecular mechanisms of how these CXXC domains, including single CXXC domains and tandem CXXC-PHD domains, recognize distinct DNA ligands, which further supports our classification of human CXXC domains and also provides insights into selective recruitment of chromatin modifiers to their respective targets via CXXC domains recognizing different genomic DNA sequences. Our study facilitates the understanding of the relationship between the DNA-binding specificities of the CXXC proteins and their biological functions. | ||
