Studies identi fi ed a novel signal of nuclear localization (NLS) in all MSL1 protein isoforms and found that the combination of both NLS allows for its intra-nuclear focal accumulation and nuclear transport of TTC4 while all MSL1 isoforms affect H4K16Ac.
The MSL1 bound to Nupr1, with a moderate affinity (2.8 microM) in an entropically-driven process. MSL1 did not bind to non-damaged DNA, but it bound to chemically-damaged-DNA with a moderate affinity (1.2 microM) also in an entropically-driven process.
MSL1 (Montrer SNRPB2 Anticorps) plays an important role in mediating irradiation-induced DNA repair through formation of HAT (Montrer MGEA5 Anticorps) complexes and interaction with 53BP1 (Montrer TP53BP1 Anticorps). P8 acts as a negative regulator of this process by interacting with MSL1 (Montrer SNRPB2 Anticorps) and preventing its role on HAT (Montrer MGEA5 Anticorps) activity.
A multisubunit human histone acetylase complex that contains homologs of the Drosophila MSL proteins MOF (Montrer KAT8 Anticorps), MSL1 (hampin A), MSL2 (Montrer MSL2 Anticorps), and MSL3 (Montrer MSL3 Anticorps) was described. This complex is responsible for histone H4 lysine-16 acetylation of all cellular chromosomes.
Data show that complete removal of paternally expressed gene 3 (PEG3 (Montrer PEG3 Anticorps)) resulted in up-regulation of male-specific lethal 1 (Msl1 (Montrer OPRK1 Anticorps)) and male-specific lethal 3 (Msl3 (Montrer MSL3 Anticorps)).
Msl1 interacts with Msl3 as an extended chain forming an extensive hydrophobic interface, whereas the Msl1-MOF interface involves electrostatic interactions between the HAT domain and a long helix of Msl1.
hampin may be linked to diverse regulatory processes in the nucleus
Describes the primary structure of the protein hampin, which shares about 26% sequence identity with the Drosophila MSL1 protein. In mouse, at least five splice isoforms exist, two of which have restricted tissue specificity (testes).
