Summary: Contributes to aminophospholipid flippase activity. Involved in several processes, including actin cortical patch localization; phospholipid translocation; and retrograde transport, endosome to Golgi. Located in late endosome membrane and trans-Golgi network. Part of Cdc50p-Drs2p complex. Orthologous to several human genes including TMEM30B (transmembrane protein 30B).

What's a GeneRIF?

cryo-electron microscopy structure of the P4-ATPase Drs2p-Cdc50p; three structures are presented that represent the complex in an autoinhibited, an intermediate and a fully activated state
Title: Structure and autoregulation of a P4-ATPase lipid flippase.
Cdc50p, a membrane protein in the endosomal/trans-Golgi network compartments, is a noncatalytic subunit of Drs2p, which is implicated in translocation of phospholipids across lipid bilayers. (cdc50p)
Title: Defects in structural integrity of ergosterol and the Cdc50p-Drs2p putative phospholipid translocase cause accumulation of endocytic membranes, onto which actin patches are assembled in yeast.
activation of the Drs2p-Cdc50p flippase follows a multistep mechanism, with preliminary release of a number of constraints, possibly through the binding of regulatory proteins in the trans-Golgi network, followed by full activation by PI4P
Title: High phosphatidylinositol 4-phosphate (PI4P)-dependent ATPase activity for the Drs2p-Cdc50p flippase after removal of its N- and C-terminal extensions.
we describe the overexpression of a yeast lipid flippase complex, namely the P4-ATPase Drs2p and its associated subunit Cdc50p, in a coordinated manner.
Title: Coordinated Overexpression in Yeast of a P4-ATPase and Its Associated Cdc50 Subunit: The Case of the Drs2p/Cdc50p Lipid Flippase Complex.
Phosphatidylinositol-4-phosphate tightly controls Drs2p-catalyzed lipid transport and establish the functional relevance of the Drs2p.Cdc50p complex.
Title: Phosphatidylserine stimulation of Drs2p·Cdc50p lipid translocase dephosphorylation is controlled by phosphatidylinositol-4-phosphate.
ATP9B is able to exit the ER and localize to the TGN independently of CDC50 proteins and this protein contains a Golgi localization signal in its N-terminal cytoplasmic region
Title: ATP9B, a P4-ATPase (a putative aminophospholipid translocase), localizes to the trans-Golgi network in a CDC50 protein-independent manner.
Cdc50 proteins are integral components of the P(4)-ATPase transport machinery
Title: Cdc50p plays a vital role in the ATPase reaction cycle of the putative aminophospholipid transporter Drs2p.
These results suggest that Cdc50p-Drs2p plays an important role in the Arf1p/Gcs1-mediated formation of clathrin-coated vesicles for the retrieval pathway from early endosomes to the trans-Golgi network.
Title: The functional relationship between the Cdc50p-Drs2p putative aminophospholipid translocase and the Arf GAP Gcs1p in vesicle formation in the retrieval pathway from yeast early endosomes to the TGN.
Drs2 or cdc50 null mutatations cause a loss of plasma membrane PS asymmetry. Loss of plasma membrane asymmetry is a secondary consequence of disrupting protein trafficking.

NP_010018.1

Endosomal protein that interacts with phospholipid flippase Drs2p; interaction with Cdc50p is essential for Drs2p catalytic activity; mutations affect cell polarity and polarized growth; similar to Lem3p; CDC50 has a paralog, YNR048W, that arose from the whole genome duplication
