Protein Name:
Putative lipid scramblase CLPTM1
|
UniprotKB/SwissProt ID: Q8VBZ3 (Q8VBZ3)
Gene Name:
Clptm1
Organism: Mus musculus (Mouse)
Function: Involved in GABAergic but not glutamatergic transmission (PubMed:29395912). Binds and traps GABAA receptors in the endoplasmic reticulum (ER) (PubMed:29395912). Modulates postsynaptic GABAergic transmission, and therefore inhibitory neurotransmission, by reducing the plasma membrane expression of these receptors (PubMed:29395912). Altered GABAergic signaling is one among many causes of cleft palate (PubMed:29395912). Might function as a lipid scramblase, translocating lipids in membranes from one leaflet to the other one (By similarity). Required for efficient glycosylphosphatidylinositol (GPI) inositol deacylation in the ER, which is a crucial step to switch GPI-anchored proteins (GPI-APs) from protein folding to transport states (By similarity). May play a role in T-cell development (PubMed:9218588)
