Summary: Enables ATPase-coupled monocarboxylic acid transmembrane transporter activity. Involved in monocarboxylic acid transport. Located in fungal-type vacuole membrane and membrane raft. Human ortholog(s) of this gene implicated in dilated cardiomyopathy (multiple); familial atrial fibrillation; glucose metabolism disease (multiple); hypertension; and hypertrichotic osteochondrodysplasia Cantu type. Orthologous to human ABCC10 (ATP binding cassette subfamily C member 10); ABCC8 (ATP binding cassette subfamily C member 8); and ABCC9 (ATP binding cassette subfamily C member 9).

What's a GeneRIF?

Deletion of YBT1 enhances in vitro homotypic vacuole fusion by up to 50% relative to wild-type vacuoles.
Title: The yeast vacuolar ABC transporter Ybt1p regulates membrane fusion through Ca2+ transport modulation.
Data show that Ybt1 is required to import the phosphatidylcholine (PC) analog NBD-PC (7-nitro-2,1,3-benzoxadiazol-PC) into vacuoles in the presence of ATP in vitro.
Title: Vacuolar import of phosphatidylcholine requires the ATP-binding cassette transporter Ybt1.

Preferred Names: bile acid-transporting ATPase YBT1

NP_013052.1

Transporter of ATP-binding cassette (ABC) family; targeted to vacuole via AP-3 pathway; involved in bile acid transport; negative regulator of vacuole fusion; regulates release of lumenal Ca2+ stores; similar to mammalian bile transporters; YBT1 has a paralog, VMR1, that arose from the whole genome duplication
