NVJ1-VAC8 nucleus-vacuole junction 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
Nucleus-vacuole junction complex, a membrane contact site formed between perinuclear and vacuolar membranes. Mediates essential cellular processes such as piecemeal microautophagy of the nucleus (PMN), a selective autophagic recycling process stimulated by carbon or nitrogen starvation through the target of rapamycin signaling pathway. Under these conditions, the region of the nucleus in the vicinity of NVJs invaginates into the vacuolar lumen and forms a bleb-like structure, which is released as a vesicle and eventually degraded by vacuolar hydrolases. NVJs are also involved in lipid metabolism by recruiting the two lipid-modifying enzymes, oxystereol-binding proteins homology OSH1 (P35845) involved in nonvesicular lipid trafficking and the enoyl-CoA reductase TSC13 (Q99190) that mediates the synthesis of very-long-chain fatty acids.
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.

catabolic process, lipid metabolic process, membrane

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.
