Nucleus-vacuole junction protein 1

UniProtKB accession:  P38881

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in the formation of nucleus-vacuole junctions (NVJs) during piecemeal microautophagy of the nucleus (PMN) (PubMed:10888680, PubMed:12529432, PubMed:16912077). NVJs are interorganelle interfaces mediated by NVJ1 in the nuclear envelope and VAC8 on the vacuole membrane (PubMed:10888680, PubMed:12529432, PubMed:16912077). Together, NVJ1 and VAC8 form Velcro-like patches through which teardrop-like portions of the nucleus are pinched off into the vacuolar lumen and degraded by the PMN process (PubMed:10888680, PubMed:12529432, PubMed:16912077, PubMed:28533415). Acts also as an outer-nuclear membrane receptor for OSH1 and TSC13 (PubMed:15367582, PubMed:15958487, PubMed:16912077, PubMed:28319008).
