Protein: Tetratricopeptide repeat protein 7B (TPR repeat protein 7B) (Tetratricopeptide repeat protein 7-like-1) (TPR repeat protein 7-like-1) (Q86TV6)
Organism: Homo sapiens (Human)
Function: Component of a complex required to localize phosphatidylinositol 4-kinase (PI4K) to the plasma membrane. The complex acts as a regulator of phosphatidylinositol 4-phosphate (PtdIns(4)P) synthesis. In the complex, plays a central role in bridging PI4KA to EFR3B and HYCC1, via direct interactions.
Subcellular location: Cytoplasm, cytosol {ECO:0000269|PubMed:23229899}. Cell membrane {ECO:0000269|PubMed:23229899}. Note=Localizes to the cytosol and is recruited to the plasma membrane following interaction with EFR3 (EFR3A or EFR3B) (PubMed:23229899). {ECO:0000269|PubMed:23229899}.
