The function of Ensembl gene identifier ENSG00000068724 (TTC7A, tetratricopeptide repeat domain 7A) is as follows. Component of a complex required to localize phosphatidylinositol 4-kinase (PI4K) to the plasma membrane (PubMed:23229899, PubMed:24417819). The complex acts as a regulator of phosphatidylinositol 4-phosphate (PtdIns(4)P) synthesis (Probable). In the complex, plays a central role in bridging PI4KA to EFR3B and HYCC1, via direct interactions (By similarity). {ECO:0000250|UniProtKB:Q86TV6, ECO:0000269|PubMed:23229899, ECO:0000269|PubMed:24417819}.
