Scaffold subunit of the histone acetyltransferase (HAT) Enok complex which has histone H3 acetyltransferase activity (PubMed:27198229). As part of the Enok complex, associates with the Elg1 RFC-like complex and down-regulates its PCNA-unloading function to promote the G1/S transition (PubMed:27198229). May also play a role in maintaining the protein levels and stability of enok (PubMed:27198229). Component of the Enok complex composed of at least Br140, enok, Eaf6 and Ing5 (PubMed:27198229). As part of the Enok complex, interacts with elg1 and the Elg1 RFC-like complex (PubMed:27198229).
