ACE2 / YLR131C Overview
- Standard Name
- Systematic Name
- SGD ID
- Feature Type
Transcription factor required for septum destruction after cytokinesis; part of the RAM network that regulates polarity and morphogenesis; NES phosphorylation by RAM network kinase Cbk1p blocks nuclear exit in mother cells during the M/G1 transition, causing asymmetric localization to daughter cell nuclei, and increased Ace2p activity; phosphorylation by Cdc28p and Pho85p prevents nuclear import during cell cycle phases other than cytokinesis; Spt16p is required for nuclear exclusion during G1

Gene Ontology Details
GO Annotations consist of four mandatory components: a gene product, a term from one of the three
Gene Ontology (GO) controlled vocabularies
Biological Process, and
Cellular Component), a reference, and an
evidence code. SGD has manually curated and high-throughput GO Annotations, both derived from the
literature, as well as computational, or predicted, annotations. Click "Gene Ontology Details" to view

Phenotype annotations for a gene are curated single mutant phenotypes that require an observable
(e.g., "cell shape"), a qualifier (e.g., "abnormal"), a mutant type (e.g., null), strain background,
and a reference. In addition, annotations are classified as classical genetics or high-throughput
(e.g., large scale survey, systematic mutation set). Whenever possible, allele information and
additional details are provided. Click "Phenotype Details" to view all phenotype annotations and
evidence for this locus as well as phenotypes it shares with other genes.
- Non-essential gene; null mutant shows bipolar budding pattern, increased cell size, cell separation defects and abnormal colony shape
Interaction annotations are curated by BioGRID and include physical
or genetic interactions observed
between at least two genes. An interaction annotation is composed of the interaction type, name of the
interactor, assay type (e.g., Two-Hybrid), annotation type (e.g., manual or high-throughput), and a
reference, as well as other experimental details. Click "Interaction Details" to view all interaction
annotations and evidence for this locus, including an interaction visualization.
- The ace2 null mutant is viable; the null mutant of paralog swi5 is viable; the ace2 swi5 double mutant is viable, but shows decreased expression of some genes.

- ACE2 encodes a transcription factor that is a member of the C2H2 zinc finger class. At the end of mitosis, Ace2p acts specifically in daughter cells to activate transcription of genes such as CTS1, SCW11, DSE2, DSE3, and DSE4, encoding chitinases and glucanases that are required to destroy the septum and allow mother and daughter cells to separate after budding. It also activates expression of BUD9 and DSE1, both involved in bud site selection. Ace2p also represses transcription of the G1 cyclin Cln3p, causing daughter cells to have a lengthened G1 period to allow sufficient growth before budding. Ace2p activity is regulated by its nuclear localization, which in turn is controlled by phosphorylation. During anaphase and early telophase, phosphorylation of the nuclear localization sites of Ace2p, mediated by mitotic cyclin-dependent kinase, prevents Ace2p from entering the nucleus. In late telophase, these sites are dephosphorylated by Cdc14p, allowing Ace2p to enter both mother and daughter nuclei. Its nuclear export sequence (NES) is then phosphorylated by Cbk1p specifically in daughter cell nuclei, causing Ace2p to accumulate there. Phosphorylation by Cbk1p at an additional site increases transcription activation by Ace2p. Later in G1, the NES of Ace2p is dephosphorylated, allowing Ace2p to exit the nucleus, after which it is sequestered in the cytoplasm. Ace2p has a paralog, Swi5p, which also acts at the end of mitosis but regulates a distinct set of genes.
Expression data are derived from records contained in the
Gene Expression Omnibus (GEO), and are first log2
transformed and normalized. Referenced datasets may contain one or more condition(s), and as a result
there may be a greater number of conditions than datasets represented in a single clickable histogram
bar. The histogram division at 0.0 separates the down-regulated (green) conditions and datasets from
those that are up-regulated (red). Click "Expression Details" to view all expression annotations and
details for this locus, including a visualization of genes that share a similar expression pattern.
