TAF1 RNA polymerase II, TATA box binding protein (TBP)-associated factor (TAF1) is a gene that encodes a protein that functions as a transcriptional co-activator. The protein is also involved in the recognition of transcriptional promoters and the modification of general transcription factors (GTFs). Missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame deletions are observed in cancers such as endometrial cancer, intestinal cancer, and stomach cancer.

TAF1 is altered in 2.92% of all cancers with breast invasive ductal carcinoma, colon adenocarcinoma, lung adenocarcinoma, cutaneous melanoma, and breast invasive lobular carcinoma having the greatest prevalence of alterations [3].

The most common alterations in TAF1 are TAF1 Mutation (2.65%), TAF1 Amplification (0.29%), TAF1 E277dup (0.47%), TAF1 C280S (0.08%), and TAF1 Loss (0.11%) [3].
