In this paper, we reflect on the disciplinary contours of contemporary sociology, and social science more generally, in the age of ‘big and broad’ social data. Our aim is to suggest how sociology and social sciences may respond to the challenges and opportunities presented by this ‘data deluge’ in ways that are innovative yet sensitive to the social and ethical life of data and methods. We begin by reviewing relevant contemporary methodological debates and consider how they relate to the emergence (...) of big and broad social data as a product, reflexive artefact and organizational feature of emerging global digital society. We then explore the challenges and opportunities afforded to social science through the widespread adoption of a new generation of distributed, digital technologies and the gathering momentum of the open data movement, grounding our observations in the work of the Collaborative Online Social Media ObServatory project. In conclusion, we argue that these challenges and opportunities motivate a renewed interest in the programme for a ‘public sociology’, characterized by the co-production of social scientific knowledge involving a broad range of actors and publics.

Histone acetylation has been recognized as an important post‐translational modification of core nucleosomal histones that changes access to the chromatin to allow gene transcription, DNA replication, and repair. Histone acetyltransferases were initially identified as co‐activators that link DNA‐binding transcription factors to the general transcriptional machinery. Over the years, more chromatin‐binding modes have been discovered suggesting direct interaction of histone acetyltransferases and their protein complex partners with histone proteins. While much progress has been made in characterizing histone acetyltransferase complexes biochemically, cell‐free (...) activity assay results are often at odds with in‐cell histone acetyltransferase activities. In‐cell studies suggest specific histone lysine targets, but broad recruitment modes, apparently not relying on specific DNA sequences, but on chromatin of a specific functional state. Here we review the evidence for general versus specific roles of individual nuclear lysine acetyltransferases in light of in vivo and in vitro data in the mammalian system. (shrink)

Acetylation of histones is an essential element regulating chromatin structure and transcription. MYST (Moz, Ybf2/Sas3, Sas2, Tip60) proteins form the largest family of histone acetyltransferases and are present in all eukaryotes. Surprisingly, until recently this protein family was poorly studied. However, in the last few years there has been a substantial increase in interest in the MYST proteins and a number of key studies have shown that these chromatin modifiers are required for a diverse range of cellular processes, both in (...) health and disease. Translocations affecting MYST histone acetyltransferases can lead to leukemia and solid tumors. Some members of the MYST family are required for the development and self‐renewal of stem cell populations; other members are essential for the prevention of inappropriate heterochromatin spreading and for the maintenance of adequate levels of gene expression. In this review we discuss the function of MYST proteins in vivo. (shrink)
