The Tudor protein survival motor neuron (SMN) is a chromatin-binding protein that interacts with methylated lysine 79 of histone H3.
Spinal muscular atrophy (SMA) is a muscular disease characterized by the death of motoneurons, and is a major genetic cause of infant mortality. Mutations in the SMN1 gene, which encodes the protein survival motor neuron (SMN), are responsible for the disease. SMN belongs to the Tudor domain protein family, whose members are known to interact with methylated arginine (R) or lysine (K) residues....
متن کاملDynamic regulation of histone H3 methylated at lysine 79 within a tissue-specific chromatin domain.
Post-translational modifications of individual lysine residues of core histones can exert unique functional consequences. For example, methylation of histone H3 at lysine 79 (H3-meK79) has been implicated recently in gene silencing in Saccharomyces cerevisiae. However, the distribution and function of H3-meK79 in mammalian chromatin are not known. We found that H3-meK79 has a variable distribut...
متن کاملThe survival of motor neuron (SMN) protein interacts with the mRNA-binding protein HuD and regulates localization of poly(A) mRNA in primary motor neuron axons.
Spinal muscular atrophy (SMA) results from reduced levels of the survival of motor neuron (SMN) protein, which has a well characterized function in spliceosomal small nuclear ribonucleoprotein assembly. Currently, it is not understood how deficiency of a housekeeping protein leads to the selective degeneration of spinal cord motor neurons. Numerous studies have shown that SMN is present in neur...
متن کاملThe Yng1p plant homeodomain finger is a methyl-histone binding module that recognizes lysine 4-methylated histone H3.
The ING (inhibitor of growth) protein family includes a group of homologous nuclear proteins that share a highly conserved plant homeodomain (PHD) finger domain at their carboxyl termini. Members of this family are found in multiprotein complexes that posttranslationally modify histones, suggesting that these proteins serve a general role in permitting various enzymatic activities to interact w...
متن کاملInvolvement of survival motor neuron (SMN) protein in cell death.
Infantile spinal muscular atrophy (SMA) is caused by mutations in the survival motor neuron (SMN)1 gene. We investigated the role of human (h) SMN protein on cell death in PC12 and Rat-1 cells. hSMN prolonged cell survival in PC12 cells deprived of trophic support and in Rat-1 cells induced to die by activation of the proto-oncogene c-Myc, to similar magnitude as Bcl-2 or IAP-2. While hSMN was ...
