This domain is found in Histone-lysine N-methyltransferase, H3 lysine -4 specific from Saccharomyces cerevisiae (SET1) and similar proteins predominantly from yeast. SET1 is the methyltransferase subunit of the COMPASS (Set1C) complex that plays a role in telomere length maintenance and transcription elongation regulation [1]. This entry represents the RNA-binding domain (RBD), which shows an alpha-beta structure.	Domain
