The function of TNRC6A (trinucleotide repeat containing adaptor 6A, ENSG00000090905) is as follows. Plays a role in RNA-mediated gene silencing by both micro- RNAs (miRNAs) and short interfering RNAs (siRNAs). Required for miRNA- dependent repression of translation and for siRNA-dependent endonucleolytic cleavage of complementary mRNAs by argonaute family proteins. As a scaffolding protein, associates with argonaute proteins bound to partially complementary mRNAs, and can simultaneously recruit CCR4-NOT and PAN deadenylase complexes. {ECO:0000269|PubMed:16284622, ECO:0000269|PubMed:16284623, ECO:0000269|PubMed:17596515, ECO:0000269|PubMed:17671087, ECO:0000269|PubMed:19056672, ECO:0000269|PubMed:19304925}.
