Histone H3 lysine 4 methyltransferase KMT2D.

ABSTRACT: Histone-lysine N-methyltransferase 2D (KMT2D), also known as MLL4 and MLL2 in humans and Mll4 in mice, belongs to a family of mammalian histone H3 lysine 4 (H3K4) methyltransferases. It is a large protein over 5500 amino acids in size and is partially functionally redundant with KMT2C. KMT2D is widely expressed in adult tissues and is essential for early embryonic development. The C-terminal SET domain is responsible for its H3K4 methyltransferase activity and is necessary for maintaining KMT2D protein stability in cells. KMT2D associates with WRAD (WDR5, RbBP5, ASH2L, and DPY30), NCOA6, PTIP, PA1, and H3K27 demethylase UTX in one protein complex. It acts as a scaffold protein within the complex and is responsible for maintaining the stability of UTX. KMT2D is a major mammalian H3K4 mono-m
