SAS acetyltransferase complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.

Summary
Histone acetyltransferase (HAT) complex capable of acetylating both free histones and nucleosomes, although the nucleosomal HAT activity of SAS complex is relatively weak. Exclusively acetylates Lys-16 of histone H4 and may provide a barrier to Sir (silent information regulator) proteins that would prevent adjacent euchromatic regions from being transcriptionally inactivated. The complex appears to assemble in the nucleus, following the separate import of the components.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.

acyltransferase activity, transferase activity, chromatin organization, histone modification, peptidyl-amino acid modification, protein acylation

Biological Process

Manually curated GO annotations reflect our best understanding of the basic biological process for this protein complex. Manually curated annotations are assigned by curators based on published papers when available, or by curatorial statements if necessary. Curators periodically review all manually curated GO annotations for accuracy and completeness.

Shared Annotations

This diagram displays Gene Ontology terms (green) that are shared between the given macromolecular complex (black) and other yeast complexes (yellow). Note: No diagram is shown ("No shared annotations") if there are less than 2 shared GO annotations between this complex and any other complexes.
