Protein: Membrane-anchored lipid-binding protein LAM6 (Lipid transfer at contact site protein 1) (Lipid transfer protein anchored at membrane contact sites 1) (Q08001)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: Involved in regulation of various organellar membrane contact sites. May be involved in sterol transfer between intracellular membranes. Selectively transports sterols between membranes in vitro. Involved in stress-dependent formation of sterol-enriched vacuolar membrane domains.
Subcellular location: Endoplasmic reticulum membrane {ECO:0000269|PubMed:26001273}; Single-pass membrane protein {ECO:0000255}. Note=Localizes to intracellular puncta representing endoplasmic reticulum-mitochondrion membrane contact sites (ERMES), nucleus-vacuole junctions (NVJ) and vacuole-mitochondria patches (vCLAMP) (PubMed:14562095, PubMed:25987606, PubMed:26001273, PubMed:26119743). Localization to ER-mitochondria contacts is dependent on TOM70/TOM71, and localization to ER-vacuole junctions on VAC8 (PubMed:25987606). {ECO:0000269|PubMed:14562095, ECO:0000269|PubMed:25987606, ECO:0000269|PubMed:26001273, ECO:0000269|PubMed:26119743}.
