This domain is found in bacteria, archaea and eukaryotes, and is approximately 50 amino acids in length. It contains an evolutionary conserved signature W-X-Y-X6-11-GPF-X4-M-X2-W-X3-GYF, the site of interaction with proline-rich peptides. Family members include RME-8 (Required for receptor-mediated endocytosis 8), a DNAJC13 protein. RME-8 was first identified as a protein that is required for endocytosis in Caenorhabditis elegans. It coordinates the activity of the WASH complex with the function of the retromer SNX dimer to control endosomal tubulation [1]. Family members found in Arabidopsis include Arabidopsis trithorax-related3 (Atxr3), also known as set domain group 2 (Sdg2). It is the major enzyme responsible for H3K4me3 in Arabidopsis and SDG2-dependent H3K4m3 is critical for regulating gene expression and plant development [2]. Another family member found in Arabidopsis is Tic56. It is an essential subunit of a 1-MDa protein complex at the inner chloroplast envelope membrane [3]. Furthermore, Tic56 is important for rRNA processing and chloroplast ribosome assembly [4].
